Using the Z88 Extender Card with an EPROM Programmer
Although I am showing this card being used with the Willem Universal EPROM Programmer, these techniques and instructions may be used with other models.
Solder the required components onto the card.
For 1M cards
A small piece of wire or ribbon cable is used to connect the A19 signal to the programmer to the 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.
For 512K cards
The 34 way connectors are shown fitted. They are used with a shorting plug (with pins 1 - 18 connected) to pull up A19 to Vpp when programming the 512K Flash cards.Use an existing Flash card to read the data and then verify it. Make sure that all your soldered joints are good ones as bad ones will produce errors when testing the card as well as testing your patience. If you get any data errors, check all your connections and soldered joints.
