Modifying Z88 Extender Card
Programming different Cards
On the previous EPROM Programmers, the footprint could be set independently from the device. This is no longer the case.
The DIL header that fits into the programmer to the Z88 card has the footprint for the 512K Flash chip. When using different chips, the footprint needs to be changed to match the pin-outs of the footprint that the programmer is expecting.
A switch is used to change the pin-outs depending on which chip is being programmed.
