Subject: Proper Method for Running Benchmark and Diagnostics Programs
Date: 06/04/93
Page(s): 1 of 1
PSB No: S-0158
Originator: MWT
This bulletin describes the proper method for running any benchmark or diagnostics
programs. This applies to any computer system.
In most cases, the computer should be started using an MS-DOS boot diskette
that’s ‘clean’ - in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.
The appropriate executable can then be run, either from diskette or hard drive.
There will be some exceptions to the above rule. In attempting to benchmark or
troubleshoot any add-on that requires a device driver (CD-ROM, local area network,
etc.), obviously the necessary device driver(s) must be loaded. Also, some
programs will require a minimum number of FILES or BUFFERS to be defined in
the CONFIG.SYS file. Such programs will usually display this requirement if they
are run without the necessary CONFIG.SYS file.
For the most consistent results, use the absolute minimal boot configuration that’s
allowed by the hardware being tested.

Installation of the board in most of the units was quick and simple to do when
following the installation instructions accompanying the boards. Installation of
the SOTA 386si in the Equity I and the Equity II is rather difficult. Due to the
amount of disassembly required, we strongly recommend that only Authorized
Service Centers install the board in the Equity I and Equity II.
Installation Instructions
Equity I
1. Remove the following from the main unit:
a) upper case
b) rear panel
c) front panel
d) FDD/power supply block.
2. Follow instructions for a standard installation for the SOTA 386si in an
8088 - based system. Take care to fold the SOTA connector cable so as
not to prevent reassembly. The cable is sturdy and will tolerate being
folded.
3. Reassemble the main unit and go through the testing and initialization
procedure outlined in the SOTA manual.
Equity II
1. Remove the following from the main unit:
a) upper case
b) rear panel
c) front panel
d) FDD/power supply block.
2. Follow instructions for a standard installation for the SOTA 386si in an
8086 - based system. Take care to fold the SOTA connector cable so as
not to prevent reassembly. This will necessitate routing the cable so that it
does not conflict with the power connection to the main system board.
The cable is sturdy and will tolerate being folded.
3. Reassemble the main unit and go through the testing and initialization
procedure outlined in the SOTA manual.

Q. Does the APEX 100 have a serial interface port?
A. Yes, an IBM PC- compatible (25 - pin connector) serial port is standard
with the APEX 100 and can be used to connect a serial device such as
an external modem, serial mouse or a serial printer.
PSB No: S-0097
Page: 2 of 8
Q. What kind of printer can I use with the APEX 100?
A. The APEX 100 includes an IBM PC - compatible parallel interface which is
used to connect any printer or plotter with a standard parallel interface.
An IBM PC- compatible parallel printer cable (not included) is required to
connect a printer to the computer.
Epson currently offers outstanding printers in the ActionPrinter line. The
T - series printers are 9 - pin printers with near letter quality print. The T1000 is an 80 column printer and the T750 is a 136 column printer. The
L- series printers are 24 - pin printers with superb letter quality print. The
L1000 is an 80 column printer and the L750 is a 136 column printer.
Q. What type of hard disk drive does Epson use with the APEX 100\20 and
what is the average disk access time.
A. Epson uses a 3.5” (5.25” frame), 20 MB, Miniscribe 8425, MFM hard disk
drive with an average access time of 69ms. The average power draw is
10 watts.
Q. Can a hard disk drive be added to the APEX 100 model?
A. Yes, you can either replace the lower floppy disk drive with an internal
half height hard disk drive (5.25” frame) and IBM PC/XT- compatible
controller or install a hard disk card. One advantage to installing a
hardcard is that you keep both floppy drives which comes in handy for
disk copying. In either case you will use an I/O expansion slot because
the hard disk drive requires a separate hard disk controller card while the
hardcard’ plugs into an I/O expansion slot. We recommend a hard disk
which draws 14 watts or less.
Another thing which you must consider, if you decide on using a hardcard
is the size (width) of the hardcard. Most hardcards take up more than
one slot, usually 1 - 1/2 slots, which means they will fit in one slot if the
board next to them is a half length board.
The Plus Development
hardcards are very thin so they will fit regardless of what type of board is
in the adjacent slot. A less expensive 1 - 1/2 slot hardcard which we have
tested in the APEX 100 is the Standard Brand hardcard. This hardcard is
available in both 20MB (Flashcard - 20) and 30MB (Flashcard - 30) models.
We recommend using a Western Digital (Model WD1002A- WX1) hard disk
controller card, as this model has been tested with the APEX 100.
PSB No: S-0097
Page: 3 of 8
Q. Can a hardcard be installed in addition to a hard disk drive?
A. Yes, but you must be sure that you do not mix MFM and RLL type hard
drives and you must be sure that the power supply is not overloaded by
using low powered hard disk drives (less than 12 watts avg. each). The
hardcard must also have a jumper for selecting it as drive 2 to avoid
conflict with the first hard disks drive’s controller.
Q. What hard disk controllers can I use?
A. The Western Digital (WD1002A- WX1) hard disk controller is recommended
for use in the APEX 100 for MFM type HDDs. Do not use the WD1002XTGEN controller as there are known compatibility problems. RLL type
hard disk drives require RLL controllers. For MFM disk drives larger than
20MB, the WD1002A- WX2 hard disk controller with Western Digital’s
SuperBios ROM should be used.
Q. What type of floppy disk drives does the APEX 100 have and what kind
of floppy diskettes should I use?
A. The APEX 100 - series computers use half - height, 5 1/4”, 360KB floppy
disk drives.
Make sure to use only double - sided, double-density,
soft- sector, 48 TPI floppy diskettes. The diskette boxes are usually
marked DSDD or 2S - 2D, Soft- Sector, 48TPI. New blank diskettes must
be formatted using the FORMAT command on the MS- DOS utilities
provided before being used.
Q. Can I use other types of floppy disk drives with the APEX 100?
A. The Epson 3.5”, half - height, 720KB floppy drive (Epson Model code
A112A - AA) has been tested with the APEX 100 computer and is
compatible (available from Epson Computer Products dealers).
5.25”, 1.2MB and 3.5”, 1.44MB, half - height floppy disk drives are not
supported with the APEX 100 personal computer in its standard
configuration. Third party external drives can be used for this requirement.
Q. Is it possible to disable the APEX 100 floppy disk controller?
A. Yes, move jumper J1 on the system board from position A to position B.
PSB No: S-0097
Page: 4 of 8
Q. Can I add an external floppy disk drive to the APEX 100?
A. Epson does not currently manufacture an optional external floppy disk drive
for the APEX 100, however, the following companies manufacture external
3.5” and 5.25” floppy disk drives which are compatible with the APEX 100.

available through Epson Accessories, Inc. at 1 - 800 - 873 - 7766, or at your
local software store.
Q. Can I install a Math- Coprocessor chip and what type do I need?
A. A Math-Coprocessor chip is an option which speeds up the floating point
math functions used in many spreadsheet and math - intensive software
applications. It can be purchased at electronic parts retailers and computer
stores (Epson America Inc. does not supply them). An Intel 8087- 1
Math - Coprocessor chip which runs at 10MHz is recommended for use with
the APEX 100 computer. The Math-Coprocessor chip is installed in the
socket provided at I.C. location 3M on the APEX 100 system board.
Q. Can I use an IBM Enhanced style keyboard with the APEX 100?
A. Yes, you may use a third- party “enhanced- style” keyboard such as the
IBM XT- 101, NorthGate C/T - 101, Datadesk Turbo - 101, Keytronics 101,
5150 and 5151 or the standard PC/XT type 84 - key keyboards by selecting
the proper dip switch setting on the front panel of the APEX 100.
Q. What kind of mouse works with the APEX 100?
A. There are many IBM PC- compatible mice that will work with the APEX
100. Most manufacturers make two different types. A bus mouse comes
with its own interface board and takes up an I/O expansion slot in the
computer. A serial mouse plugs directly into the serial port and doesn’t
require any I/O expansion slots. Microsoft, Logitech, Genius, and Mouse
Systems are popular models that can be used.

Q. Can I use the APEX 100 Monochrome Monitor (Model # AP - 1040) with
other IBM PC - compatible computers?
A. The Apex 12” Monochrome monitor (Model AP - 1040) uses a TTL video
signal which is IBM PC - compatible and can be used with other computers
that have a monochrome TTL video board. It should not be confused,
however, with the earlier Apex composite video monochrome monitor (Model
# AP - 1010A) which is not compatible with the APEX 100 video board.
Q. Can I use the Apex color monitor with other IBM PC- compatible
computers and what are the specifications?
A. The Apex 13” color monitor (Model AP - 1020B) is an IBM PC - compatible,
16 color, RGB, dual function monitor which can be set up for either color
or green screen mode with a switch on the rear panel. It has a 640 x
200 (black and white) or 320 x 200 (4 color) graphics dot resolution. It
can display 16 colors in 80 column x 25 row text mode. The dot pitch
is .52mm.
Q. What other monitors are compatible with the APEX 100 and is it possible
to use a television set?
A. Most IBM PC- compatible RGB color or TTL monochrome monitors will
work with the video board provided with the APEX 100 computer.
Composite monitors are not supported.
IBM PC- compatible EGA and VGA monitors can also be used if the
existing video board is replaced with an EGA or VGA video board (available
from computer dealers). The front panel dip switches 1 - 5 and 1 - 6 must
be set to the ON position, otherwise the computer will give one long beep
and two short beeps and no video will be displayed.

where can I buy them?
A. Most IBM PC/XT- compatible option boards will work in the APEX 100
computer. You should visit a computer retail store to see a wide range
of products. The products must state specifically that they are IBM
PC/XT - compatible. Since there are many different manufacturers, it is
impossible for Epson to test all option boards available to insure
compatibility. We recommend that you purchase boards from a dealer who
will exchange the board if for some reason it is not compatible.
