IMPORTANTS
Plug and unplug the emulation PODs with TARGET SYSTEM
switched off.
When possible power the emulator through the TARGET SYSTEM (
Power Option JUMPER shorted and external power connector not used
). This is a good method to avoid LATCH-UP problems.
When you are using external power feature you must supply power to
emulator and TARGET SYSTEM at the same time.

SOFTWARE SETUP
3.1 Software
Setup
Software setup in Windows 3.x / Windows95 can be made launching the
executable file SETUP.EXE present in the distribution diskette.
If you have Windows 3.x based system you can use FILE MANAGER, if
you have Windows95 you can start the setup process selecting the
SETUP.EXE from the computer resources. ( Open the resource window,
open the 3.5 floppy drive and double click on SETUP.EXE file ).
The setup process is self-explanied..
If you need the DOS version of software you have to copy the files
contained in the directory <\dosonly> of distribution diskette in your work
directory. However, the executable file datazap!.exe is sufficent to use
the emulator.

Note 1
To use 28 Pin devices in EVEN/ODD mode you can use the ADP 32-28 adapter for the ODD POD.
For the EVEN POD you can use the ADP LARGE 28-32 adapter connecting the EVEN probe in the
socket marked ‘U1’ and shorting the jumper ‘JP1’, always present in the adapter, on position 1-2.
At this point you have to insert a 28 Pin socket in the 32 Pin socket in the adapter target-side. Take
care to connect the Pin 14 of the new socket with the Pin 16 of the POD socket.
If the dimensions of the ADP LARGE 28-32 are excessive it’s possible to build a simple 32-28
adapter. See the appendix of this manual for construction details.
Also, you can find the ADP-LARGE 28-32 schematic always in the appendix of this manual.

THE 16 BIT
EVEN/ODD
MODE
ROMShock User’s Manual
In a typical 16 Bit system , the system memory can be organized as two
8 Bit banks. This means that the address lines driven by the micro are
shifted of one position. (Address A1 of micro conencted to address A0
of the memory, address A2 of micro connected to address A1 of
memory and so on .. ). Obviosly all the address lines except the line A0
are commons for the two devices.
In fact, the address line A0 has the word‘s LOW / HIGH selection
functionality.
With the 16 Bit EVEN/ODD mode you can emulate two 32 Pin EPROM
devices.
Also you can emulate two 28 Pin devices using the two adapters
included in the KIT ( ADP LARGE 28-32, ADP 32-28 ).
A typical EVEN/ODD 16 Bit system is shown in Figure 6.
Figure 6 -16 Bit EVEN/ODDconfiguration

ROMShock User’s Manual
5.3
THE SMALL 8
BIT MODE
The ROMShock’s circuitry it’s formed by two distinct DATA sections.
This means that if one section is unused, all the memory relative to that
section is lost. This is not a problem if the requested emulation memory
is limited to 512 Kbytes (256KB for the S model). If you need more
emulation memory you can use the LARGE 8 BIT MODE.
The SMALL mode foresees the using of the POD#1 only (EVEN POD ).
To use 28 Pins devices it’s necessary to use the adapter ADP 32-28.
5.4
THE LARGE 8
BIT MODE
The LARGE 8 BIT mode may be activated using the special adapter
ADP-LARGE 28-32 ( see Figure 4 ) included in the KIT. This adapter
permits the use of all the available memory to emulate devices from
27C256 (32Kx8) alla 27C080 (1Mx8).
If you have the S model the emulation is limited to 27C040 ( 512Kx8 ).
5.5
THE LARGE
ADAPTER
Below is reported the ADP-LARGE 28-32 layout. The ADP-LARGE 2832 adapter may be used to emulate 28 Pins devices too. For this
purpose use the SMALL MODE with the EVEN POD only. The JUMPER
( in the high side of the board ) must be configured in position 1-2. With
32 Pin devices, the JP1 JUMPER must be configured in position 2-3.

WINDOWS 3.1 / 95 PROGRAM INTERFACE
The Windows ROMShock program could be considered as an accessory
to keep in the Windows’s desktop giving the possibility to activate code
loading at any moment..
A typical work enviroment could consist of a DOS-Shell where you
launch your compiler or assembler and the ROMShock program.
When the compiling phase is terminated you simply have to press the
LOAD button on the ROMShock program’s panel to activate the code
loading.
In the program’s panel, there are four buttons plus a big button with the
product’s logo. Pressing the big button will display the general program
information. The four buttons activates respectively the fundamental
functions of the program.

Pressing this button will access the Windows standard load-dialog.
You can select Intel Std/Ext, Motorola S, or binary file type.
Pay attention! The file extension is independent from in wich the file is
interpreted. The translating mode must be setted in the
CONFIGURATION DIALOG in this same section described.
The currently selected file could be saved as DEFAULT file at program
startup by simply giving a configuration save command.
The configuration-save command is available trough the ‘Configuration’
menu with the ‘Save Configuration’ selection.
The ‘ Open File’ function is available through the File Menu too
The TRANSLATE function can be used to convert files. This is useful
during the devolpement process to generate programmer’s files .BIN or
.IMG. The TRANSLATE function can process Intel STD/EXT and
Motorola S 16/24 Bit formats.
If the ‘Auto Detect’ option in the configuration DIALOG is active, the
software automatically checks for the .HEX/.S native extensions.
If one of these extensions is found the program activates the associated
conversion.The program, by default, generates a binary file (.BIN).
If the Image option in the configuration dialog is active the program will
generate a image file (.IMG).
A image file is a file with dimension equal to the difference between the
highest address and the lowest address, addresses obviously refer to
the input file. The parts not covered by addresses are filled with the
constant 255 ( 0xFF ).
RESET Button The RESET button permits a transition on signals RST and RTS#,
present on connector in the back panel. By connecting one of these
signals on the RESET pin of your TARGET MICROPROCESSOR, it will
be possible to reset your TARGET by simply pressing this button.
LOAD Button
The LOAD button loads, into the emulator, the file currently selected.
Pressing this button a progress-bar will appear.
At the same time the LOADING LED in the front panel will light.
During the LOAD session the RST and RST# signal becomes active.

DATAZAP!.EXE The -Mx switch sets the EMULATION MODE. Refer to SECTION 5 and
Table 1 for details.
SWITCHES
SWITCH -Fx ( FILE FORMAT )
This switch sets the input file format. The software can translate three
formats : Intel STD/EXT, Motorola S 16/24 Bit and BINARY files. The
software automatically checks for the natural extensions .HEX /.S /
.BIN. If one of these extensions are found the software activates the
associated conversion. If the extension is ommited and the -Fx switch
wasn’t used , the software assumes for default the .BINARY format.
SWITCH -R ( GENERATE RESETPULSE )
The -R switch is an alternative mode to send a RESET PULSE to the
TARGET SYSTEM without operating directly on the HARDWARE.
Using this option the program simply generates a transition on outputs
RST / RST# ( these outputs obviously are to be connected to the
microprocessor reset input pin ). The implse width is about 250ms.
SWITCH -Nn ( PORT NUMBER )
Use this switch to select the parallel port where the emulator is
connected.
SWITCH -Ohhhhhh ( File Offset )
With this switch it’s possible to add a LOAD OFFSET to the input file
loading addresses.This offset must be supplied in HEXADECIMAL
FORMAT in the range from 0(h) to FFFFF(h).
SWITCH -T ( TRANSLATE MODE)
The -T switch selects the FILE TRANSLATE OPERATING MODE.
This mode allows the use of the datazap!.exe program as a file
converter utility. Detail about this mode is explained in SECTION 8.
SWITCH -I ( IMAGE MODE)
This switch, in combination with the switch -T tells to the program to
generate IMAGE files ( .IMG ) instead of the BINARY default format (
.BIN ).
20
MicroSHADOW
Research
ROMShock User’s Manual
SWITCH -Skkkk ( BINARY FILE SIZE )
This switch, in combination with the switch -T ( Don’t use with the -I
switch ) sets the output file size. The areas, uncovered by any
address, relative to the input file, will be filled with the constant FF(h).
The kkkk parameter must be supplied in decimal notation in the range
from 32 to 1024.
SWITCH -H ( HELP PAGE )
The program syntaxs and a short description of the main features can
be displayed using this switch.
7.3
CARICAMENTO
DEI FILES CON
DATAZAP!.EXE
Loading a file on the emulator with datazap!.exe is really easy.
We assume that your linker give as output a Intel STD/EXT or Motorola
.S or a pure BINARY file.
To start the loading you just have to write :
datazap! FileName.ext -Mx
Pay attention to the emulation mode selected by the switch -Mx.
Once started, the program will display some input file parameters and
the data transfer will begin. On your display you can see the transferred
byte count and at the end you can obtain the elapsed time.
The LOADING LED will be active for all the transfer time. At the same
time the RST / RST# outputs are active. This allows the TARGET CPU
in the RESET STATE to be kept.
Terminated the transfer, the RST and RST# outputs change their state
and the LOADING LED turns off ( CPU RUNNING STATE ).

SECTION 8
FILES CONVERSION USING DATAZAP!.EXE
8.1 FILES
CONVERSION
As just mentioned, datazap!.exe can be used as a file converter utility.
This is really useful at the end of the developing process to generate
the programmer BINARY or IMAGE files to obtain the final ROM /
EPROM. In TRANSLATE mode, the software can detect the Intel
STD/EXT, Motorola S 16/24 Bit files formats.
The software automatically checks for the .HEX / .S native extension
and if one of these extensions are found, the program activates the
associated conversion. The program generates a pure BINARY file
(.BIN) or a BINARY IMAGE file if the -I switch is used.
An image file is a file of dimension equal to the difference between the
highest address and the lowest address, addresses obviously refering
to the input file. The parts not covered by any addresses are filled with
the constant 255 ( 0xFF ).
To invoke a conversion just write :
datazap! FileName.ext -T [ -I ]

HARDWARE CONSIDERATIONS
In this section you can find useful information about the ROMShock
Hardware. This information may be useful if you want to use
ROMShock with particolar TARGET systems in non-standard working
enviroment. If you have system instability, it is best if you analyze the
interface section first.
No emulators in the world can grant 100% compability with the
original emulated device.

Building
retails
The adapter is formed by a 32 Pin socket and a 28 Pin socket.
The 28 Pin socket must be plugged below the 32 PIN socket with his
PIN 14 plugged in the PIN 16 of the 32 PIN socket ( EPROM GND ). At
this point it’s sufficent to make a link between the PIN 32 of the 32 PIN
socket and the PIN 28 of the other socket ( This resolves the power
supply connection).
The resulting adapter is now ready to be placed in the POD socket.
For this adapter it is best to use lathed sockets.
