Welcome to PHC-16, the world's first truly personal computer.
PHC-16 is a full-featured IBM-compatible business computer.
It comes with:
* 256K of memory, expandable to 1280K.
* 5-1/4 inch physical (diskette) drive and 3.5
inch physical (diskette) drive plus a unique
internal electronic RAM drive with up to 360K memory.
* Optional add-on physical (diskette) drive.
* Full 80 column, 25 line LCD screen.
* RS-232 serial and parallel printer connections.
RGB and composite ports for optional monitors.
* Optional built-in modem.
Optional add-on expansion unit.
* Reads from and writes to a 3.5 inch floppy disk.
With all these features, you might expect a desktop full of
equipment. Instead, PHC-16 is as portable as a briefcase. It's
compact design, low weight, (only 12 pounds), and optional
battery pack, make it an ideal companion for the business person
on the go. Use it on a plane, train, boat, taxi, bus, or in your
hotel room. Take it home for the evening, or take it around the
world. It's always ready.
Best of all, PHC-16 is easy to use. It uses Microsoft DOS and
runs most programs written for the IBM PC. Add your favorite
application software, and you re off and running.
This manual, the PHC-16 Guide to Operations, gives you
instructions for setting up and operating your PHC-16. If you
have never operated a computer before, a section for the first
time user introduces you to a few helpful basics.
It is beyond the scope of this manual to tell you everything you
may need to know about computers, MS-DOS, BASIC, and application
programs. Since there are many books available for the IBM PC,
we have tried to give you a quick primer on PC operations while
concentrating only on those items that differ from IBM PC
operations.
This section is only for those who have already opened their
PHC-16, are experienced using IBM PC or compatible computers and
PC or MS-DOS, and hate to read manuals. Follow these few steps
to get off to a fast start:
1. Press the keyboard release latch to detach the keyboard.
2. Install batteries in the keyboard. Press any key and make
sure the light in the upper right corner comes on. The
keyboard is wireless, but needs a clear path between the
keyboard and computer.
3. Insert the AC adapter into the computer. Turn the AC
adapter switch on.
4. Press the screen release latch and adjust the screen angle.
5. Insert the DOS diskette from the DOS manual, or any bootable
diskette, into the PHC-16's physical (diskette) drive.
MAKE SURE THE LABEL ON THE DISKETTE FACES TOWARD THE REAR OF
THE COMPUTER AND THE NOTCH IS UP. Push the diskette into
the slot until 1t clicks. Press in the button labeled
"PUSH" at the top of the drive until it clicks.
6. Turn ON the PHC-16 power switch at the back and lower right of
the computer. Press in the left side of the switch so the
red line on the right side of the switch is showing.
7. Depending on the internal switch settings, the PHC-16
elther:
* Automatically sets up a RAM drive as Drive B, and
installs DOS, or
* Displays a screen that lets you set up a RAM drive.
Follow the instructions on the screen.
You are now up and running!
USING THE RAM DRIVE FOR A TWO DRIVE SYSTEM
The RAM drive enables the PHC-16 to work like a two-drive
system. Since the RAM drive is much faster than the physical
diskette drive, we recommend that you load your application
software program diskette onto the RAM drive and use the physical
drive for your data. Since the default drive is A, you can
toggle the drive designations of A and B between the physical and
RAM drives by pressing the CTRL, Left Shift, and D keys
simultaneously and continue to use A as the default drive. Or,
you can change the default drive to B. Here are some examples:
l. Your word processor programs are on one diskette and your
data is on another. Insert your word processor program
diskette in the physical drive and copy the files to the RAM
drive like this:
COPY *.* B:
Remove the word processor diskette and insert the data
diskette in the physical drive. Swap drive designations by
pressing CTRL, ALT, and D at the same time. The RAM drive
(your word processor) is now A and the physical drive (your
data) is now B. Load your word processor (for Wordstar, for
example, type WS and press ENTER) and operate as you would
on any two-drive system.
2. Your spreadsheet is copy protected and won t copy to the RAM
drive. Instead, copy your data (or only the files you need)
to the RAM drive, and use the spreadsheet program diskette
in the physical drive. REMEMBER TO COPY YOUR DATA BACK TO
YOUR DATA DISKETTE WHEN YOU RE THROUGH, BEFORE TURNING OFF
THE PHC-16!
3. Your filer system is on one diskette and your data 1s on
another. But once the filer programs load, that diskette is
never read. Insert the filer system diskette in the physical
drive and load it as you would normally. Swap drive
designations, remove the program diskette, and insert your
data diskette in the physical drive.
To display the help screen showing switch settings and keyboard
options press the CTRL, Left Shift, and T (for Teach) keys at the
same time.
CAUTION: BE SURE TO ALLOCATE ALL 360K TO THE RAM DRIVE BEFORE
USING THE DISKCOPY COMMAND! Although it appears that DOS has
copied the entire 360K disk, it has not and may result in missing
data or produce unpredictable results!

Getting Started
A. Unpacking
You probably have already unpacked your PHC-16 computer box,
but check this list of items you should have found there:
The PHC-16 Computer
The AC Power Pack
Four AA batteries for the keyboard
Remember to save your box and the packing material to use
if you ever need to ship your PHC-16.
WARNING: Transporting the PHC-16 without the cardboard
insert (or a scratch diskette) installed in the physical
(diskette) drive and the release button pushed in may invalidate
the physical (diskette) drive warranty.
B. Setting Up
1. The Keyboard
To release the keyboard, find the keyboard release latch and
press down. The keyboard is completely detachable. Remove it
and place it in front of your PHC-16.
Press down on the keyboard
Ll
release latch to detach the | !
keyboard.
о о |
Keyboard Release Latch
The keyboard has two elevation feet on the back. Pull them out
if you want your keyboard tilted slightly.
PHC-16 keyboard is not attached to the rest of the computer.
The keyboard sends signals to the computer by infrared light beam.
The illustration below shows how this infrared light works.
Keep the keyboard in front of
your computer and don't let
anything obstruct the light
beam.
The keyboard is powered by four standard AA batteries. The
battery compartment is located in the upper left corner of the
keyboard. Find the small cover just above the gray function keys
and slide it off. Install the batteries included in your PHC-16
box, following the diagram on the inside of the battery
compartment. Replace the cover.
Press any key and the red light on the keyboard should come on.
If it doesn’t come on now, or at any time you use your PHC-16,
the batteries are dead and must be replaced. We recommend
standard AA batteries available at most convenience stores.
Always replace all four batteries at the same time.
An optional keyboard cable is available to physically connect the
keyboard to the computer if you wish to do so. This cable is
coiled and can be extended to ten feet. You still need working
batteries to power the keyboard; the cable replaces the infrared
beam.
Tips for better computing with your infrared light beam:
* Don't let anything block the beam when you are using
the keys.
* Don ‘t turn the keyboard at too great an angle. The
infrared beam will not make proper contact with the
PHC-16.
Sometimes a key may appear to be stuck. This is rare
and happens if the computer senses when the key is
pressed, but not when it is released. This is not a
mechanical error, but may occur because of some
interference between the keyboard and the computer. If
this happens, reposition the keyboard and press the key
that seems stuck again.
2. The Screen
Find the screen release latch and PRESS IT IN lightly. You can
feel it release. Now, pull the screen out until it s in
the best position for you.
Press the screen release latch
and adjust the angle of the
screen.
Screen Release Latch
Caution: Make sure the screen panel is not forced up beyond it's
limit. Also, never lift or move the computer by
grasping the screen panel.
C. A Quick Tour of PHC-16
Now that your PHC-16 is set up, let's take a quick look at all
the external switches and plugs. We'll talk about each of these
in different places in this Guide to Operations. But this
illustration lets you find your way around PHC-16 and can help
as a quick reference later.

D. For the First Time User
If PHC-16 is the first microcomputer you have used, this section
introduces you to a few basics.
We don't want to bore you with the history of computers or bury
you with technical computerese. But we do want you to understand
enough about how your PHC-16 works so that you can logically
work your way through new situations and use your computer more
efficiently. If you are already familiar with computers, you may
want to skip this section.
l. How Your Computer Works
Your PHC-16, like any computer, has a single purpose: to
manipulate data. A computer is not very smart--its mathematical
ability is no better than that of a pre-school child. But it is
so astonishingly fast that it can process in seconds what might
take humans days or weeks. And it can store data more
conveniently and compactly than we have traditionally done with
paper. These attributes, and its portability, make the PHC-16 a
very powerful and productive business tool.
Every computer system is built around the Central Processing Unit
This is the box, big or little, that holds the processing chips
and electronic circuits. “The Central Processing Unit, as the name
implies, does the processing or computing.
Your body is like a computer system. Your brain receives
information from your senses, analyzes it and sends instructions
to your muscles. In this way you communicate with your
environment. In a similar manner, your computer system needs
devices to communicate with you, to receive instructions and data
from you and to send the results back to you in a form you can
understand. These devices are call peripherals. Here's a simple
diagram of a computer system:
Most computer systems con-
sists of these parts. | | - { =) _ qu

— il —
keyboard -
Screen
Your PHC-16 has two built-in peripherals: a keyboard Lor you to
enter data and a screen for you to see the results. You can add
a printer to print the results on paper, and you can add a modem
so your PHC-16 can exchange information with other computers
over telephone lines. With a modem, for example, you could
compose memos or write reports in your hotel room and send them
py telephone to your home office thousands of miles away.
2. Software
Your computer system is called hardware and the instructions that
tell the computer what to do are called software. These
instructions are grouped together in programs to do a certain
job, like word processing, and are usually called application
programs.
There are some other software programs that make the computer
system work, called system software. The most important system
software you will use is the operating system. The operating
system manages your data and instructions for application
software as they move through the computer system.
3. How Data 1s Stored
Inside the computer is an area called internal memory where data
is stored while the computer manipulates the data. The computer
can transfer data into and out of internal memory very quickly.
This is called reading and writing.
But your computer's internal memory is limited. You need a way
to store large amounts of data. Your PHC-16 uses diskettes.
These are sometimes called floppy disks. Diskettes store data
permanently, and you can use as many diskettes as necessary to
store your data. Other computers use cassette tapes or hard
disks. .
Data storage capacity is measured in kilobytes or K. A byte is
one character of data. One kilobyte, or K, equals not 1000 bytes
or characters as the name "kilo" implies, but 1024 bytes.
The internal memory of your computer is divided into two sections.
One area is reserved for portions of the operating system and
hardware instructions. This area is called Read Only Memory, Or
ROM. The other section of memory is a working storage area where
the computer stores instructions and data. This area is called
Random Access Memory or RAM. RAM in your PHC-16 can be
subdivided, or partitioned, into working storage RAM and a RAM
drive.
4. Things to Know About the Keys
Think ol your keyboard as a sophisticated typewriter. It has
all the regular keys, plus some others. Most of the keys work
just like a typewriter, but there are a few exceptions.
keys that Look Alike
On typowriters, the letter O and the
number zero are interchangable. Not |
so with computers. Make sure you type E
the right character in commands and E 0
file names. On your keyboard and on =
your screen the zero has a diagonal
line through it.
The computer also knows the difference
between a lower-case L and the number 1. 1
Sometimes the computer requires you to
enter only numbers or only letters. Be
careful to use the right key.
The Spacebar
Find the spacebar on your keyboard. The
spacebar works like one on a regular
typewriter, but it also has special functions.
Blanks are important to a computer and
the spacebar is used to enter those
blanks.
The Shift and Caps Lock Keys
PHC-16 has two shift keys marked with up
arrows and located about where you would Tenes
find them on a regular typewriter. Use I и
either shift key to type upper-case letters
or to type the symbols in the upper portion
of the number keys. Use the Left Shift key
with the CTRL key to perform special features.
The Caps Lock key is located just below the
right shift key and works like the
shift lock key on a typewriter. It lets you
type only capital letters until you press 1t
again. Unlike a typewriter, 1t only affects
letter keys. You still have to press the
shift key to use the symbols in the upper
portion of the number keys. To turn off the
Caps Lock, press the key again.
The Function Keys
Notice the darker gray keys across the top left side of your
keyboard. These keys take on different "functions" epending
on the software you are using on your computer.
ее
The Arrow Keys and Numeric Keypad
The medium gray keys in the upper
right corner of your keyboard serve two
functions. The four keys marked with arrows —
are called the Up, Down, Left, and Right В ||
Arrow keys, and allow you to move the cursor HOME -
around your screen.
When you press the key marked NUM LOCK, the
numeric keypad is ON. This means that
the number keys in the upper right corner of all - >
your keyboard become a numeric keypad,
similar to the keys on a calculator. Press
the NUM LOCK key again to turn the numeric
keypad OFF.

The ENTER Key
The large key on the right side of your
keyboard is used when you have finished
typing a command. After you press ENTER,
the computer starts processing the command you
just typed. The ENTER key also works like a E
carriage return on a typewriter. For this
reason it's called the RETURN key on some
computers.
с
5. About Diskettes and the Physical Drive
The PHC-16 uses 5-1/4 inch diskettes. Diskettes are
sometimes called floppy disks. PHC-16 uses double-sided, double
density diskettes.
A permanent, protective black jacket holds the diskette.
And diskettes are stored in paper envelopes that provide
additional protection.
Information and software, the instructions to the computer, are
stored on diskettes. The computer can read the existing data
on the diskette, or you can add more data in unused space on the
dra ket te
because important information is stored on diskettes, they must
be protected. Follow these cautions:
x Do not try to remove the permanent black jacket.
* Do not touch the exposed surface of the diskette (see
illustration). It is important that this surface stay
clean. A speck of dust or a fingerprint could destroy
data.
* Always return your diskettes to the paper envelopes.
This helps protect them.
* Store all diskettes away from heat and magnetic
field sources such as telephones and dictating
equipment.
* Always make copies of your diskettes for additional
protection. These are called back-up copies.
Instructions for making backup copies are found in
Chapter 4: Operations.
* Always label your diskettes with a felt-tipped pen.
Pencils or pens could damage the diskette. Use the
adhesive labels that come with a box of diskettes.
* Do not leave diskettes in a parked car on a very hot
day or expose them to temperatures below 50 F (10 C).
* Do not bend diskettes.
To use a diskette, insert it in the PHC-16 physical (diskette)
drive with the notch up and the label facing away from you. The
drive 1s the slot on the right side of your computer.
Slide the diskette into the disk Jun
drive until it clicks. Then press
the little square button until it
Es AT Keane Button
clicks. ss ST
Diskette
While the RAM drive (discussed in the next section) is
electronic, the diskette drive is mechanical. To avoid confusion
between the two drives, this manual always calls the diskette
drive the physical drive.
To insert the diskette in the physical drive, follow these steps:
1. Press the release button (labeled PUSH) at the top of
the physical drive. Then remove the white cardboard
protector from the PHC-16 physical drive. Grasp the
flap and pull it out.
2. Hold the diskette with the LABEL FACING THE BACK OF THE
COMPUTER AND THE NOTCH UP, and slide 1t into the
physical drive.
3. When it is all the way in the slot you will hear a
faint click.
4. Press the release button (labeled PUSH) at the top of the
physical drive until you hear another click. This is
like closing the door to the physical drive.
6. An Electronic Drive -- The RAM Drive
PHC-16 includes a built-in electronic drive that works just like
the mechanical diskette drive, and gives you the versatility and
convenience of a two-drive system. This electronic drive is
called a RAM drive because it uses a portion of RAM. PHC-16
lets you set aside up to 360K of RAM to use to store programs and
data, just like the diskette drive. When you start up, PHC-16
asks you to designate how much RAM to allocate to the RAM drive.
You may assign from 0 to 360K in 8K increments. Or, you can turn
switch SW2-1 ON so that PHC-16 will automatically allocate the
full 360K to the RAM drive whenever you start up.
When using the RAM drive, remember to always copy any data you
want saved to a diskette before you turn the power off. All RAM
SEEOTY including the RAM drive, is lost when power is turned
off.
Caution: Be sure to allocate all 360K to the RAM drive before
using the DISKCOPY command. Using DISKCOPY to copy to a RAM
drive of less than 360K may cause data loss or unpredictable
results.
l'or detailed instructions on using the RAM drive, see the section
on "Using the RAM Drive" in Chapter 4: Operations.
Ho Turning the Power ON and OFF
How that your PHC-16 1s unpacked and set up, and you ve learned
the keys and some important terms and concepts, you re ready to
turn your PHC-16 on and put it to work.
rour PHC-16 operates on either household AC electricity, or with
1 battery pack. The AC power pack is standard equipment and was
hipped with your PHC-16. The battery power pack 1s optional.
|. inserting the Power Source
Both the AC pack and the optional battery pack are inserted in
exactly the same place and in the same way:
l. Make sure the on/off switch on the back of the PHC-16 is
OFF (press down on the right side of the switch so the
red line does not show). It should come shipped turned
OFF, but check to make sure.
2. insert the power pack (either battery or AC) into the
power slot located on the left side of PHC-16. The
power pack can only be put in one way. If it doesn’t
go in at first, flip it over.
3. Push the power pack all the way in until you hear it
click.
4. Turn the power pack switch ON.

2. Removing the Power Pack
To take out either the standard AC pack or the optional battery
power pack, follow these steps:
1. If you have been using the computer, make sure all data
has been saved, and that any data on files in the RAM
drive has been copied back to a diskette.
2. Remove any diskette in the physical drive.
3. Turn the on/off switch on the back of the PHC-16 OFF.
4. Turn the power pack switch OFF.
5. Find the gray button just to the left of the power pack
and press it. The power pack should pop out of its
slot part way.
6. If nothing happens, use your other hand to press in
slightly on the power pack while you press the gray
button. This releases the pressure on the catch and it
should pop out part way.
7. Pull the power pack the rest of the way out.
Remove any diskettes and turn
the Datavue power off.
Press the release button to
release the power pack and
slide it all the way out.

F. Start Up
PHC-16 is easy to turn on. Follow these steps:
1. Install either the AC adapter or the battery power pack
as described in the steps above. If you are using the
AC adapter, plug it into an electrical outlet.
2. Turn the on/off switch on the power pack ON.
3. Turn the on/off switch on the back of PHC-16 ON (press
in on the left side of the switch so that the red line

You can, and certainly will want to, reserve some RAM for a RAM
drive. The RAM drive turns your PHC-16 into a much more
versatile, two-drive computer.

If you have the standard 256K of memory, however, you must manage
your memory carefully. With 256K, the maximum size your RAM
drive can be is 192K. This is less than your diskette drive
(360K) and only leaves 64K for working storage--too little for
most software available today.

Increasing memory to 768K or 1280K gives ample RAM for a full RAM
drive and enough working storage to run the larger and more
complex software appearing on the market.

Another feature you'll want to use if you have enough memory is
reserved memory. Turning switch SW2-5 ON will reserve 24K of
RAM to save your screen so that when you return from using a CTRL
Left Shift feature, your screen will be as you left it.
Otherwise, you return to a blank screen. PHC-16 uses part of
the 24K as a data buffer for the remote (dumb) terminal mode.
With this switch ON, the three rightmost squares or diamonds on
the screen will be replaced with three pyramid symbols, and the
reserved memory line will read 24K. These CTRL Left Shift key
functions are explained fully in the next chapter.

There are three switch blocks, each containing eight slider
switches, located in the modem compartment on the left side of
the computer. Remove the cover to see the switches:
These switches are set at the factory, and won t need to be
changed if you re just starting to use your PHC-16. After you
become familiar with your PHC-16 and want to tailor it to your
needs, or to add options, you may want to change some settings.
To change a switch, use a pencil, ballpoint pen, bent paper clip,
or other pointed object. Always move the switch gently, sliding
it up for ON or down for OFF.

Chapter 3 Traveling With PHC-16
PHC-16 is a good traveling companion. With the optional battery
power pack installed, it weighs only 14 pounds and 1s small
enough to take almost anywhere.
In addition, the optional built-in modem (see Chapter 6: Options) lets
you stay in touch with other computers when you are on the road.
This section gives you a few suggestions and cautions to make
traveling with the PHC-16 easy and efficient.
A. Carrying Case
When you re on the go with PHC-16, the optional carrying case
provides protection for the computer and makes it easier for you
to carry.
The convenient shoulder strap leaves your hands free. Also, the
carrying case is designed with an outside pocket to carry
batteries or other equipment securely.
B. The Battery Pack
A battery power pack can be purchased as an option for PHC-16.
It is installed exactly the same way as the AC power pack.
Caution: Be sure to recharge the battery as soon as the red LED
light flashes. If the battery discharges totally, you will not
be able to fully recharge it again.
To recharge the battery power pack, use the charger adapter clip
that comes with the battery power pack and the AC power pack that
comes standard with PHC-16. The charger adapter clip connects
the battery pack to the AC power pack.
You can fully recharge the battery while in the PHC-16 only when the
computer is turned off.
To recharge the battery pack while it is in the computer, follow
these steps:
1. Put the battery pack in the PHC-16 exactly the same
way as the AC power pack.
2. Plug one end of the Charger Clip into the computer on
the side to the right of the screen. Clip the other
end onto the AC power pack.
3. Plug the AC power pack into an electrical outlet.
While the battery pack is in the
computer, charge it this way.
When the battery power pack is not in the PHC-16 follow these
steps to recharge the battery:
1. Put the clip on the battery and plug the other end of
the clip into the AC power pack.
2. Plug the AC Power Pack into an electrical outlet.
While the battery pack is out of Charger Chip
the computer, charge it this
way. /
| | 3
© Die a.
Battery Power Pack AC Power Pack
Ch —— — D
It takes about three hours to recharge the battery pack. If you are
recharging the battery while it's in the PHC-16, you can charge
to only 85% of capacity. It is best to let the battery discharge
to 10-15% of power capacity frequently before recharging.
C. Battery Indicator
Immediately under the LCD screen is a small red indicator light.
The light begins to blink when the battery is low. Press the
CTRL, Left Shift, and B keys at the same time to sce the
percentage of power capacity remaining.
There are two ways to keep your data safe as power declines:
Plug the AC adapter or auto adapter into a power source
and the charge clip into the side of the computer.
Operate in this manner or exchange the discharged
battery for a fully charged battery and disconnect the
adapter.
OR:
Save your data, turn the computer off and insert a new
battery.
D. Traveling Hints and Suggestions
*
When traveling with PHC-16 or moving it, always insert
the white cardboard protector in the physical drive.
This protects the physical drive from any damage.
Or, insert a scratch diskette turned 90 degrees.
When you travel by plane, carry PHC-16 with you.
NEVER CHECK IT IN BAGGAGE CLAIM!
Don't leave PHC-16 in a parked car for long periods if
the temperature is either very hot or very cold. The
screen display may not work if it has been in extreme
temperatures. If this happens, let the computer return to
normal room temperature (which might take about an
hour) before using it.
If you need to ship PHC-16, pack it in the box that it
came from the factory in, if possible.
Dropping the PHC-16 or hitting it sharply may damage
the LCD screen or physical drive alignment. Your
warranty will not cover abuse.

which is also called MS-DOS, or just DOS, for
of several programs which allow you to manage

Turn the power on and DOS will load into internal memory. This 1s
called starting the computer. It is also called booting.
Starting with he computer turned off 1s called a cold boot.
Pressing the reset button performs a cold boot without having to
turn the on/off switch OFF and ON again. During a cold boot, all
data in RAM, which includes working storage and the RAM drive, 1s
lost.
You may, at any time, restart with the computer running by
pressing CTRL, ALT and DEL simultaneously. This is called a
warm boot. Caution: restart only when necessary because you
will loose any data in working storage; you will not, however,
loose any data in the RAM drive.
After a few seconds, DOS loads and displays the date and time.
DOS takes these from the PHC-16 internal clock. If you want
to change the date and time, change them through the World Clock,
or using the Clock Tests option from the Diagnostics diskette.
You can’t change them in DOS.
DOS displays this prompt:
A>
This 1s called the A prompt. It means that Drive A (your
physical drive) is the drive that DOS will read from or write to.
This 1s called the default drive because DOS will work from
Drive A unless you tell it otherwise.
The ">" in the prompt means that DOS is waiting for you to enter
a command or file name following the >.
You may change the default drive from the physical drive to the
RAM drive. At the A>, type B: and press ENTER. DOS will then
display the B prompt:
B>
This means that DOS will read from and write to the RAM drive,
until instructed otherwise.
You'll learn more about why this is useful later in the chapter
under DOS Commands.
CAUTION: Before you continue to work with DOS, make a working, or
backup, copy. Then, if you accidently damage your diskette, your
DOS master will still be intact. See the section "Making a Backup
Copy of Your DOS Diskette" toward the end of this chapter for
step-by-step instructions.
B. About the DOS keyboard
Usually.you-will use the standard keyboard functions for DOS that
you learned about in Chapter 1. This includes the keys tor
letters, numbers and special characters. DOS doesn't
differentiate between upper or lower case letters for commands
and file names, so you may use either and get the same results.
Here are some of the special keys you will use with DOS. Sce your
DOS manual for a complete list.

C. Summary of DOS Commands
Farlier in this chapter you learned that DOS is a data manager.
DOS organizes data into files. You name the file, and DOS
assigns storage space in memory or on a diskette.
DOS organizes your data in a way similar to the way you would
organize data in a filing cabinet. Each drawer contains file
folders that contain your data--sometimes a page or two, and
sometimes many pages. You organize the folders in some logical
way, and label each file folder and file drawer so you can find
your data easily.
DOS puts your data into computer files and stores them in a
logical fashion either in memory or on a diskette. DOS maintains
a directory on each so it can easily retricve your data.
Every file must have a name. On a diskette, or in memory, no two
files can have the same name. Two files may have the same name,
however, if they are on different diskettes, or on one diskette
and in memory. In your file cabinet, for example, two files
called "miscellaneous" would be OK if one were in the drawer for
household expenses, and another was in the drawer for business
expenses. If they were in the same drawer, however, you couldn't
tell” them apart.
The name you give to a file in DOS must follow this format: FORMAT
XXXKXXXX .YYY

where xxxxxxxx is the filename from 1-8 characters, and and tracks, a

o the letters of the alphabet
o the numbers 0 through 9
o these special characters:
The filename and extension may not contain blanks and must be d:
separated by a period. For example, NEW-MEMO.DOC is valid while
NEW MEMO DOC is not.
1. DOS Commands
Although your DOS manual discusses the DOS commands in detail, /S
here are some of the common commands that you'll use often:
FORMAT - sets up a diskette so it is ready to receive files.
DIR - list all the files on a diskette or on the RAM disk.
DISKCOPY and COPY - copy a file or files from one location to another.
ERASE - erases a file or files from a diskette or the RAM disk.
TYPE - displays the contents of a file on your screen.
/8 or /B
The following pages briefly describe how to use these commands.
Options arc shown in brackets. These options are not required,
but provide flexibility in using the commands. Only the most
commonly used options are discussed; see your DOS manual for a
complete description.
Although the names of the commands are printed here in caps so
they stand out on the page, you may type them in either upper or /V
lower case letters. Options are shown in brackets to indicate
they are not required. When you type the command, do not enclose
the options in brackets! Leave a space between the command and
options, but don't leave spaces between options. Finally, after For example,
you type the command and options, be sure to press ENTER. diskette with
When you use a file name with a command, you may specify a
specific file, or you may specify a series of files by
substituting a special character for all or a portion of the
filename and extension. These special characters are called
wildcards. The most commonly used wildcard is the asterisk (*).
You'll see how to use this character in the next few pages.
o Everything in brackets is optional, but allows you several
5 & EE) (IL options in formatting. Here's what they mean:
Drive designation of the diskette you want
formatted. With a one-drive system, this will
always be A (the RAM drive 1s formatted
automatically). Leave this option out if you are
working from the A>.
This option will copy the system files (the files
DOS uses to start your PHC-16) onto the formatted
diskette. This is very helpful when you are using
application software, like a word processor. If
you copy the application programs onto a diskette
formatted with the system files, the diskette
becomes self-starting. This means that you don't
have to start with the DOS diskette and then take
the DOS diskette out and put the application
diskette in, because everything you need will be
on the same diskette.
If you don’t use these options, DOS will format
the diskette with 9 sectors, or 360K total
capacity. However, if you tried to use these disks
with DOS 1.0 or 1.1, these earlier versions of DOS
couldn't read the diskette. Using /8 ог /B tells
DOS to format the diskette with only 8 sectors.
This limits storage capacity to 320K, but allows
the diskette to be read by any version of DOS.
This option allows you to enter an ll-character
volume name for the diskette, providing you format
the diskette for 9 sectors.
entering, at the A>, FORMAT /S/B will format a
eight sectors and will contain the system files.
DIR
The DIR or directory command displays the names of all the files
stored on a diskette or on the RAM drive. The DIR command has
several handy options:
DIR [d:][filename[.ext]][/W]
Typing DIR alone lists all the file names on the diskette or on
the RAM drive, in a single column.
d: specifies a drive other than the default drive.
filename [.ext] allows you to display specific file names,
or, by using a wildcard, specific groups of
file names. For example, DIR *.BAS would
list all file names with an extension of BAS,
and DIR JAN*.* would list all file names
starting with JAN.
/W lists all file names in five columns across
the screen. This lets you display a large
directory on a single screen.
DISKCOPY and COPY
These commands copy files from one location to another. With a
PHC-16 with one physical drive, you can copy from a diskette to
a diskette, from a diskette to the RAM drive, or from the RAM
drive to a diskette.
Copying is one of the most frequently performed tasks you will do
with DOS. Backing up your data and your application programs 1s
critical. Your data is always subject to accidental loss, and
diskettes may be damaged and eventually will wear out.
Copying files also allows you to keep one copy of a data file as
a master file, and use another copy as a work file. And, copying
allows you to organize files on diskettes to meet your own individual
needs.
DISKCOPY copies the contents of one diskette (or the RAM drive) to
another diskette, exactly as they are on the first. Since
DISKCOPY formats as it copies, it erases all data on the diskette
(or RAM drive) you are copying to. Be careful!
Use DISKCOPY to backup your data files at the end of each work
session. When copying to the RAM Drive, you must have
allocated a full 360K to the RAM drive for DISKCOPY to work
properly. Use the format:
DISKCOPY [d:] [d:]
а: а: The first d: is the drive you are copying from,
or the source drive. The second d: is the
drive you are copying to, or the target drive. If
you are using Drive A for both, omit these options.
COPY copies one file, or using wildcards, a series of files, from
one diskette to another. Although there are many options that can
be used with COPY, the most commonly-used format is:
COPY [d:]ffilename[.ext]] [d:]
d: is the drive you are copying from. Omit it if
you are copying from the default drive.
filenamel.ext] is the name of the file you are copying. You
may name a specific file to be copied, such as
MEMO.DOC. You may select a series of files to be
copied, such as *.BAS (all files with the
extension of BAS). Or, you may copy all files by
using *.* as the filename and extension.
d: is the drive you are copying to, or the
target drive.
Using the COPY command can get complicated and confusing. If you
have any doubts about what you want to do, see your DOS manual
before you try it!
ERASE (or DEL) removes files from your disk. The format is:
ERASE [d:][filename[.ext]]
d: is the drive where the file you want to erase is
located. Omit it, and DOS will look on the default
drive.
filename[l.ext] is the name of the file you want to delete.
As with other commands, you may use a wildcard to
erase a series of files, but use extreme caution!
For example, typing MEMO*.* will erase all memo
files, but there may be a MEMO file you wanted to
keep, and you may not realize it until it's too late.
TYPE
TYPE is a very useful command, because it displays the contents
of a file. Use the form:
TYPE [d:][filename|.ext]]
d: 1s the drive on which the file is located.
filename[.ext] is the name of the file you want to display.
The file scrolls from beginning to end automatically. Use the
CTRL and NUM LOCK keys together to stop the file from scrolling.
Press any key to continue.
A Final Word About DOS Commands
If you look at the directory of the DOS diskette, you ‘11 see a
list of filenames that match the commands discussed in the
previous pages. These files contain programs that perform the
functions described under the commands.
DOS commands are of two types: resident and non-resident, or
external. When you start the system with the DOS diskette, some
of the commands, or program files, are loaded into memory. These
are called resident commands, because they reside in memory and
will run without having the DOS diskette in the physical drive,
or loaded onto the RAM drive. DIR, COPY, ERASE, and TYPE are all
resident commands.
Other DOS commands are called external because they are not in
memory and will run only if you have the DOS diskette in the
physical drive, or have the program file loaded into the RAM
drive. FORMAT and DISKCOPY are external commands.
D. Making a Backup Copy of DOS
Now that you have read about several DOS commands, you are ready
to use these commands to make a working, or backup, copy of your
DOS diskette. Follow these steps, and besides making a copy of
DOS,
you can practice using the commands and see how DOS prompts
you to swap diskettes into and out of the physical drive.
Use the DISKCOPY command to copy your DOS diskette.
1.
2.
10.
11.
At the A>, type DISKCOPY.
DOS prompts you with this message:
Insert source diskette in drive A:
Strike any key when ready
The DOS diskette is the source diskette. Place it in the
physical drive if it is not already there. Press any key.
DOS displays this message to let you know it's copying:
Copying 2 side(s), 9 sectors per track
After a few seconds, DOS prompts you again:
Insert destination diskette in drive A
Strike any key when ready
Remove the DOS diskette from the physical drive, and insert a
new diskette in the drive. The new diskette is the destination
diskette. Press any key.
DOS displays another status message:
Formatting target while copying
Since you are using a new diskette, DOS must format it before
copying files onto it.
After a few seconds, DOS prompts you again:
Insert source diskette in drive A:
Strike any key when ready
Remove the new diskette from the physical drive and insert
the DOS diskette. Press any key.
After a few seconds, DOS prompts you again:
Insert destination diskette in drive A
Strike any key when ready
Remove the DOS diskette from the physical drive and insert
the new diskette. Press any key.
12. After a few seconds, DOS finishes the DISKCOPY and displays
this message:
Copy complete
Copy another disk (Y/N)?
l3. Type n and DOS returns to the A>.
То make sure that the new diskette is good, compare the two
diskettes with the DISKCOMP command:
|. At the A>, type DISKCOMP and press ENTER. DOS displays
this prompt:
Insert first diskette in drive A:
Strike any key when ready
2. Insert the DOS diskette in the physical drive and press any key.
3. DOS displays this message:
Comparing 2 side(s), 9 sectors per track
4. After a few seconds, DOS prompts you again:
Insert second diskette in drive A:
Strike any key when ready
5. Remove the DOS diskette from the physical drive and insert
the new diskette. Press any key.
6. After a few seconds, DOS prompts you again:
Insert first diskette in drive A:
Strike any key when ready
7. Remove the new diskette from the physical drive and insert
the DOS diskette. Press any key.
8. After a few seconds, DOS tells you that it's finished:
Diskettes compare ok
Compare another disk (Y/N)?
9. Type n and DOS returns to the A>.
This new diskette now becomes your Working Copy DOS diskette. Put
the master DOS diskette back in the DOS manual and keep it in a
safe place.
The DISKCOMP may find errors in certain tracks and sectors on
your new diskette. If this happens, use the FORMAT command to
reformat the new diskette. If DOS finds bad sectors, throw the
diskette away and FORMAT a new diskette until you find one that
formats without bad sectors. Then repeat the DISKCOPY and
DISKCOMP steps above.
Making a Working Copy DOS diskette - Alternate Method
Another way to make a working copy of your DOS diskette is to use
the RAM drive (full 360K) as an intermediate repository. This
means you must first copy the DOS diskette to the RAM drive and
then copy to the new diskette, but it reduces the diskette
swapping required by only using the physical drive. Here's how it
works:
1. At the A>, type DISKCOPY A: B: and press ENTER.
2. DOS prompts you with this message:
Insert source diskette in drive A:
Insert destination diskette in drive B:
Strike any key when ready
3. Insert the DOS diskette in the physical drive and press any key.
4. DOS displays this message to let you know it's copying:
Copying 2 side(s), 9 sectors per track
When DOS finishes copying, it will display this message:
Copy complete
Copy another disk (Y/N)?
5. Type N and DOS returns to the A>.
6. Type B: and press ENTER to change the default drive to B.
7. At the B>, type DISKCOPY B: A: and press ENTER.
8. DOS prompts you with this message:
Insert source diskette in drive B:
Insert destination diskette in drive A:
Strike any key when ready
9. Remove the DOS diskette from the physical drive, insert a new
diskette, and press any key.
10. bos displays this message to let you know it's copying:
Copying 2 side(s), 9 sectors per track
When DOs finishes, 1t displays this message:
Copy complete
Copy another disk (Y/N)?
ll. Type N and DOS will return to the B>.
12. Type A: and press ENTER to change the default drive to A.
This completes the copying phase. Follow the DISKCOMP
Instructions above to make sure your new working copy of DOS is
ok.
К. Using the RAM Drive
PHC-16 RAM drive works like a second physical drive, so you
have the versatility of a two-drive system. We suggest that, when
you run normal application programs, you follow these steps:
Load DOS into the PHC-16.
Remove the DOS diskette.
Put the application diskette in the physical drive.
Copy the programs into the RAM drive using COPY or DISKCOPY.
Remove the application diskette from the physical drive.
Put the data diskette in the physical drive.
Change the default drive designation to B, the RAM drive.
You are now ready to start.
OAUJOU SUN —
This puts your application programs on the RAM drive where they
will run faster and allows the PHC-16 to read and write your
data to the diskette.
When you are asked for file names by the application program, be
sure to include the drive designation as part of the filename.
For example, suppose your word processor is in Drive B (the RAM
drive) and your data diskette is in Drive A (the physical drive.)
Your word processor asks you what file you want to edit. The file
you want is called MEMO.DOC and is on your data diskette. Type
A:MEMO. DOC.
Caution: Your application program may be copy-protected to
prevent piracy. This will usually prevent you from using the RAM
drive as we have just described. Always follow the installation
instructions that come with your application program.
F. Using BASIC (Not Included with PHC-16)
BASIC is a programming language that lets you write your own
programs. If you want to use BASIC to write programs, skip this
section and go directly to the optional Microsoft BASIC manual.
BASIC for the IBM and COMPAQ computers will not run on the
PHC-16. You must buy GWBASIC, Better BASIC, or some other
generic BASIC that does not depend on BIOS ROM code for
identification or support routines.
There will be times, however, when you may want to run BASIC
programs that are already written. This section introduces you to
BASIC and shows you how to load and run BASIC programs.
Caution: Before you begin using BASIC, be sure to make a back-up
or working copy of your BASIC diskette.
To use BASIC, start the PHC-16 with DOS. Remove the DOS diskette
from the physical drive and insert your working copy of the
BASIC diskette. At the A> prompt type BASICA and press ENTER. This
screen appears:
GW-BASIC 2.02

OSCREEN
Notice that the DOS A> prompt no longer appears. BASIC has it's own
prompt to tell you it's ready for your response. The BASIC prompt
is OK with the cursor on the line below it. Make sure you begin
typing at the BASIC prompt.
look at the numbers at the bottom of the screen. These numbers
correspond to the function keys, and show the BASIC commands that
are programmed for each function key. The only function keys you
need to load and run BASIC programs are F2 and F3, RUN and LOAD.
Remove the BASIC diskette from the physical drive and insert your
data diskette containing the BASIC program you want to run.
suppose it's a game with the file name FUN.BAS. Before you can
run the program you must load it. At the BASIC prompt, type
LOAD"FUN and press ENTER. BASIC will load the program and
return to the BASIC prompt. Or, if you want to use the function
keys, at the BASIC prompt, press F3. BASIC will reply with
LOAD" and the cursor will be after the ". Type FUN and press
ENTER.
To run the program, type RUN and press ENTER or press F2.
BASIC will run your program. When you exit your program, BASIC
returns to the BASIC prompt.
When you are through using BASIC, put the BASIC diskette back in
the physical drive. Type SYSTEM at the BASIC prompt and press
INTER. BASIC returns to the DOS A> prompt.
Some programs, especially games, use 40-column displays rather
than 80-column. When you exit the BASIC program and return to the
BASIC prompt, you may see a large OK and no function key commands
listed at the bottom of the screen. This means you are still in
the 40-column display mode. But you can continue to use BASIC
commands and function keys as with the BASIC screen, even though
the function key identifiers do not appear at the bottom of the
screen. If this happens, and you want to return to the BASIC
screen, insert the BASIC diskette in the physical drive, if it is
not already there, type SYSTEM and press ENTER to return to the
A> prompt, and type BASICA and press ENTER to reload BASIC.
For more information on BASIC, see your BASIC manual.

PHC-16 is a solidly constructed and thoroughly tested computer
that should give you years of trouble free operation. However,
as with any equipment, things can go wrong. If your PHC-16 is
not operating properly, you can check a number of functions
yourself.
A. Check These Things First
If your PHC-16 fails to turn on, check these things first:
* Is your computer plugged into an electrical outlet?
* Are both the on/off switch on the back of the PHC-16
and the switch on the power pack turned ON?
* Is the memory board plugged securely into the connection?
The black part of the plug must completely cover the
gold-colored prongs. Sometimes you have to press hard.
* Is the screen adjusted so you can see the memory
partition screen?
* Is the palette being used visible? Press the CTRL,
Left Shift, and S keys at the same time to cycle
through the palettes and choose the best one.
* Is the PHC-16 in the external monitor mode? Press the
CTRL, Left Shift, and M keys at the same time to turn
the external monitor mode on or off.
If your PHC-16 has been operating and suddenly stops, check
these things first:
* Is the keyboard infrared beam still pointed directly at
the computer?
* If you are using a battery power pack, has the battery
run down? The light on your computer just under the
screen comes on to warn you that the battery is low.
* If the red light on the keyboard does not come on when
you press a key, the keyboard batteries need to be
replaced. Follow the instructions and diagrams in
Chapter 1 for installing batteries.
* Sometimes application software will "lock up." Press
CTRL and BREAK keys at the same time. This should
return you to the A> prompt.
If this doesn’t work, restart by pressing the CTRL, ALT,
and DEL keys at the same time. Make sure you have a
DOS diskette or self-starting application diskette in the
physical drive before you restart. This erases
everything in working storage but keeps all data on the
RAM drive. Return to your application and continue.
If this doesn't work either, press the reset button. |
This returns you to the memory allocation screen, but
erases everything in both working storage and the RAM
drive. |

A number of options are designed specifically for use with the
PIIC-16. These are described briefly here, but specific
instructions for installing and operating them come with
the individual options.
Also, PHC-16 is completely compatible with the IBM PC. Printers
or "mice" designed for use with the IBM PC can also be used with
the PHC-16.
A. Add-On Physical (Diskette) Drive
PHC-16 has an optional second 360K byte physical drive that
attaches directly to the back of PHC-16. With the add-on drive
your system becomes a two physical drive system.
Attach the second disk drive
like this. Don't forget to
change switch SW2-6 to ON.
— В
Connector Plate
Jn Desk Drive
l. How it Works
To attach the add-on physical drive, follow these steps:
l. Attach the connector plate to the back of the PHC-16 by
putting the hooks on the plate into the slots on the
back of the PHC-16 case.
2. Attach the add-on physical drive to the plate with the
knobs on the plate and the slots on the back of the
add-on.
\. Take the connector that is attached to the add-on
physical drive and insert it into the expansion port on
the back of the PHC-16.
4. Change these switch settings:
Switch SW1-7 must be OFF
Switch SW1-8 must be ON
Switch SW3-3 must be OFF
Now when you use any software, the add-on physical drive can be
used and identified as the C drive. For example, if you put a
word processing program in the A drive, you could put another
diskette in the add-on physical drive and instruct PHC-16 to
create your text files on the diskette in the add-on physical
drive. Identify the add-on as the C drive.
B. Modem
PHC-16 offers an optional internal modem that is Bell 212A
Standard. It can communicate at either 300 or 1200 baud. It
features auto-dial, auto-answer and re-dial. It accepts Hayes-
type commands and 15 bundled with the communications software
Crosstalk XVI.
The PHC-16 built-in modem is easy to use. Install it in the
modem compartment on the left side of your computer (just below
the memory slot). It adds little weight to the PHC-16.
C. Expansion Unit
The optional expansion unit allows you to use up to three IBM PC
compatible expansion boards, and can be purchased with or without
a 10 megabyte hard drive.
If you use the expansion unit to run a monitor, be sure to turn
switch SW2-4 ON.
If you use the expansion unit to add memory, be sure to turn
switch SW3-7 or SW3-8 (or both) OFF.
Caution: When the I/O box is used to supply power to the PHC-16, make
sure the power adaptor has been disconnected. Failure to do so is
dangerous and may cause damage to the power adoptor. If the adaptor is
dameged bue to this negligence, the maker is not responsible for
replacement, even if the damage occurs during the warranty period.
р. Expanding ilemory
PHC-16 comes with 256K bytes of memory already installed, but
this can be expanded to 1280K. You can buy your PHC-16 with an
additional 768K or 1024K.
If you buy additional memory, it will be located on an expansion
memory board in the memory compartment on the left side of the
PHC-16. If you buy the full 1024K expansion (for a fully-loaded
PHC-16 of 1280K, or 1.25 MEG, total) you will probably never
need to remove the memory board.
However, if you buy the 512K expansion (768K total), you may want
to add memory at some time. You must use 256K chips, and must
add memory in banks of 256K at a time.
Open the cover to the memory board compartment on the left side
of the computer:
To remove the memory board and install more memory chips, follow
these steps:
1. Turn OFF all power to the PHC-16.
2. After opening the cover, disconnect the board
by pulling the white plastic tab a little to your left.
You 11 be able to tell when the board plug 1s
disconnected.
3. Now, slide the whole memory board out.
NI
E
The memory board really contains two individual boards bolted
together. If you bought 512K of additional memory, the lower
board will be filled with chips and the upper board will be
empty. The empty chip sockets are in two rows and are numbered
1-8 and 9-16.
Memory can only be increased in 256K increments by filling up a
whole row of eight sockets at a time. Be sure to use only 256K
chips. Install the first row of chips in sockets 1-8. If you
also install a second set, use sockets 9-16.
To install new chips, follow these steps:
l. The pins on your new chips are usually spread apart a
little too much. Before inserting, press the
pins in slightly.
2. Now, insert the chip on the board in the correct slot
as shown in this illustration.
Press the chip on the board in
the desired slot. Make sure
that the chips are all inserted
facing the same direction. The
tops (end with notch) are all to
be facing upwards, as are the
standard RAM chips already in-
serted into the board.
3. Make sure that all the chips are inserted facing the
same direction. The tops (the end with the notch)
should all be facing up, as are the chips that were
installed in your PHC-16 at the factory.
4. After you have installed the extra memory chips, insert
the board back into the slot. Notice the tracks that the
upper board should slide into.
5. Plug in the connector.
If you bought the PHC-16 with the 512K memory upgrade installed,
the switches should be set correctly, and are the same for all
total memory over 640K.
Here's a summary of possible memory combinations and appropriate

E. Color or Composite Monitor
PHC-16 contains all the circuitry necessary to use a color or
composite monitor. Plug a color monitor into the RGB jack or a
composite monitor into the composite (RCA type) jack. Both jacks
are on the back of the PHC-16.
Make sure you set switches SW1-5 and SW1-6 for your monitor.
These settings will be different for different monitors.
You can switch back and forth between the monitor and the PHC-16
LCD by pressing the CTRL, Left Shift, and M keys at the same
time.
F. Carrying Case
A carrying case designed specifically for the PHC-16 is
available in a sturdy, canvas-like cloth.
The carrying case features an outside pocket for storing extra
batteries, the PHC-16 Guide to Operations, or other
supplies.
G. Car Adapter
This option is the same design as the AC power pack that comes
standard with the PHC-16. But instead of plugging into an
electrical outlet, it plugs into an automobile cigarette lighter.
H. Keyboard Cable
An optional keyboard cable is available for use with the PHC-16.
The available cable is coiled and can be extended up to ten feet.
I. High Performance Components
You can add these components to greatly increase the performance
of your PHC-16. All are installed on the system board by
removing the case and plugging them into the appropriate socket.
See the Appendix, Technical Information, for more details.
1. 8087 Coprocessor
Adding an 8087 coprocessor can greatly increase the processing
speed of your PHC-16. The most significant increase will come
when performing complicated mathematical calculations.
Be sure to turn switch SW1-4 OFF.
2. ROM
You can add a pre-programmed 16K or 32K ROM chip. The PHC-16
will read this ROM on startup. Although programming ROM is a
complicated process and must be performed by experts, this gives
you the capability of making your own programs permanently
available on the PHC-16, independent of other storage devices.
This is called "firmware".
3. CMOS
CMOS (Complementary Metal Oxide Semiconductor) is RAM powered by
a battery to retain the data stored in it. PHC-16 comes with 2K
of CMOS, which is used to store settings for the world clock,
audio feedback, monitor, and remote terminal. You can add up to
8K to permanently store your own data. For example, you may want
to store a telephone number list for your modem.

4. Battery Backup CMOS RAM
2K bytes are standard and 8K bytes are optional.
To upgrade from 2K to 8K, turn the power off, remove the 6 screws
that hold the front and back of the case together, and remove the
socketed RAM chip (M5M5117P or equivalent) on the 1/0 board and
replace it with an 8K RAM chip (M5M5165P or equivalent).
When installing a 2K memory chip (24 pins) in the CMOS RAM socket
(28 pins), be sure that the end that is not notched is even with
the end of the socket:
Lower RAM locations (1K) are used by the system to store setup
parameters. This allows the system to power up in the same mode
as when 1t powered down.
RAM locations 0400H to 07FFH are free for the programmer (2K
standard). RAM locations 0400H to 3FFFH are free for the
programmer when the optional 8K is installed.
This memory is addressed through I/0 port addresses 27BH, 37FH,
and 370H - 377H.
The procedure is to first set address lines All, Al2 via the
port 27BH. The data on the LSB D1, DO lines are latched (DO-
>All, D1->A12).
Then set address lines A3 to Al0 through port 37FH. (DO->A3,
D7->Al0).
8 bytes of data can now be read/written directly from/to the CMOS
RAM by reading/writing any of ports 370H to 377H.
Example: Write the number 55 to location 37 in the RAM.
37 DECIMAL = 25 HEX = 100101
This corresponds to putting the following pattern on the address
bus:
Al2 А11 А10 A9 AB A7 A6 A5 A4 A3 A2 Al AO
0 0 0 0 0 0 0 1 0 0 1 0 1
MOV DX,27BH
MOV AL,O
OUT DX,AL ¡SET Al2, All
MOV DX,37FH
MOV AL,00000100B
OUT DX,AL ; SET A1O ТО АЗ
MOV DX,375H ;A2, Al, AO PATTERN IS 101B = 5
MOV AL,55 ;370H+5 = 375H
OUT DX,AL
To make it easier, there are two routines in the system BIOS ROM
that when called will do a read/write to the CMOS RAM area.
How to use:
Set the address you want to read from or write to into the DX
register.
Write: Set the data you want to write into the AL or AX
register. Do a far call to the desired routine.
Read: Do a far call to the desired routine. The data
read is returned in the AL or AX register.
F0O00:FF60 READ BYTE (AL HAS THE BYTE READ)
FOOO:FF64 WRITE BYTE (AL HAS THE BYTE TO WRITE)
FOOO:FF68 READ WORD (AX HAS THE WORD READ)
FOOO:FF6C WRITE WORD (AX HAS THE WORD TO WRITE)
The backup battery may run down if the computer is not used for
45 days or more (NICAD type). If this happens, it may be
necessary to set switch 2-3 ON to force the computer to boot up
using the LCD display when no RGB is attached.
5. DIP Switches
See Chapter 2: Customizing Your PHC-16 for the location and use
of the dip switches. This section provides technical information
about the switches.
Switch 1 is read through an 8255 chip having ports 60H, 61H, 62H,
and 63H:
* Port 60H is used as a read only port.
* Port 61H is used as a control port and can be written to
or read from.
* Port 62H is used as a read only port.
* Port 63H is the 8255 chip control port and is used to set
up ports 60H - 62H.
The relationship between ports 60H, 61H, 62H, the SWl-1 to SW1-8
settings, and the data that is read at ports 60H and 62H are as
follows:
PORT 60H PORT 61H D7=0 PORT 61H D7=1
DATA BIT
DO KEYBOARD DO 1
D1 KEYBOARD Dl SW1-4
D2 KEY BOARD D2 1
D3 KEYBOARD D3 1
D4 KEYBOARD D4 SW1-5
DS KEYBOARD DS SW1-6
D6 KEY BOARD D6 SW1-7
D7 KEYBOARD D7 SW1-8
PORT 62H PORT 61H D2=0 PORT 61H D2=1
DO SW1-3 0
Dl 1 1
D2 1 Swl-1
D3 1 SW1-2
CAUTION: Some software does direct read/write without using the
system BIOS routines. This software may not work correctly
unless SW3-2 is ON.
A 5.25 inch floppy disk drive can be attached to the back of the
case. In this configuration, it 1s necessary to distinguish
between Drive B being internal or external. After power on, the
internal /external Drive B selections can be made by setting D2 of
port 73H to l or 0.
5W3-5 and SW3-6 can be used to select different fonts. ‘Type 3
and 4 fonts are currently undefined.
Port 73H (write only) is a control port used to enable or disable
the functions selected by dip switch SW3-2 to SW3-8. "he
following are the data bit settings:
DO=0 Used to turn power to the backlit LCD (when installed) ON or OFF.
D1=0 Always supply power to the floppy disk drives
(OFF saves battery power).
D2=0 The 2nd floppy disk drive is internal.
D3=0 Internal video RAM is being used (B8000-BrFFF).
D4=0 Selects .D4=1 Selects D4=0 Selects D4=1 Selects
D5=0 USA font D5=0 Type 2 font D5=1 Type 3 font D5=1 Type 4 font
D6=0 Internal RAM is being used (40000-7FFFF), OFF for external cards.
D7=0 Internal RAM is being used (80000-BFFFF), OFF for external cards.
This allows a programmer to select these options from a program
1f desired.
6. CRT Video and LCD Video
The PHC-16 has RBG and composite video connectors out the
back. The RBG pinout is the same as the "industry standard".
The CRT video and LCD video are controlled by a V6355 controller
chip. The selection of a CRT monitor or the LCD screen is done
by reprogramming the chip and by writing to port 72H (write
only).
Port 72H also controls the reverse video and contrast on the LCD
screen.
DO=1 Lower the contrast.
Dl=1 Raise the contrast.
D2=1 Set the contrast to a mid-range value.
D3=1 Select a CRT monitor (D3=0 selects the LCD).
D4=1 Reverse the black and white on the LCD screen.
D5 Not used.
D6 Not used.
D7 Not used.
The V6355 chip has 16 palettes. Each one can be reprogrammed to
give any of an 8 level gray scale on the screen. All "colors"
can be made the same, or they can be set as desired.
The CTRL-Left Shift-S command rotates through six different
palette settings to make the LCD screen readable for a variety of
color combinations. The first five settings are fixed. The
sixth setting is user selectable; however, the desired values
must be written to CMOS RAM.
PALETTE
0 General use.
1 Enables the intensity bit for Wordstar type programs.
2 Reverses the use of the intensity bit.
3 Gives an 8-level gray scale in text mode.
4 For composite video output.
5 User definable. The default values give the same
effect as inverse video on the LCD screen (the values
are the reverse of palette 3).
RBG output will not be affected by the palette selection.
Default Palette 5 values are:
00H,70H,00H,60H,00H,50H, 00H, 40H
00H,30H,00H,20H,00H,10H,00t, 00H
