EPROM Programmer Requirements
For 512K/512K Flash RAM Cards
EPROM Programmers expect the user to program the actual chip using the supplied Zero insertion force (ZIF) socket or an adapter. The Z88 PCB Extender Card is an adapter and uses the same 32 pin DIL footprint as the 512K Flash devices. This means that as long as the EPROM Programmer can program
- A29F040A - 512K Flash
- AM29F040B - 512K Flash
DIL chips, they can be used.
The switch is set to the Right - 512K H
For 1M Flash Cards
The Am29F080 1M Flash chip can be programmed two ways.
Using a 32 pin EPROM Programmer
the Flash card may be programmed twice,
The switch is set to
- the Right - 512 DIL - for the upper half
- the Centre - 512 L - for the low half
Using a 40 pin EPROM Programmer
If the programmer has it on its list using a TSOP40 adapter with these connections
- using the active signals in the ZIF socket and the additional address line, A19 it can be used.
If all the pins are expected to be connected to the TSOP40 device, it cannot be used.
A small piece of wire or ribbon cable is used to connect the A19 signal to the programmer either to
- a single socket in the ZIF connector or
- an 8-way header on the Programmer. There are two pins that are marked, the 2nd pin from either end.
If you are using a different programmer, find out where the A19 pin is and connect the wire to that point.
Testing the EPROM Programmer
Use an existing Flash card to read the data and then verify it. If any data errors are encountered
- make sure that the switch is on the correct setting
- all the soldered joints are good
as bad ones will produce errors when testing the card as well as testing your patience.
Batronix BX32 Batupo II
This uses a single USB connection for Power and control. It has a 32 pin ZIF socket which allows it to program the 512K Flash Cards.

Willem Universal EPROM Programmer
This was the first programmer to be used. It used two connections to the Desktop computer
- USB for Power
- Parallel Cable from the LPT1 printer port.
Instructions are given for this programmer and can be used as a guide to using other programmers.
Modern computers do no longer support the parallel post.
Alternative programmers have been found.

GQ-3X EEPROM FLASH CHIP PROGRAMMER
SUPPORTS ALL WILLEM ZIF ADAPTERS
This uses a single USB connection for Power and control. It has a 40 pin ZIF socket which allows it to program the 1M and 512K Flash Cards. This is a cheaper and older alternative than the GQ-4X above. This has not been tested.

TL866A UNIVERSAL EEPROM Programmer
This uses a single USB connection for Power and control.
It has a 40 pin ZIF socket which allows it to program the 1M and 512K Flash Cards.
This has not been tested as it tests whether all the pins have been connected.
