I just bought the dual power willem eprom programmer with the 16 bit adaptor. I didnt get the diy cable set but instead I got three jumper wires. I can't figure out how to program 27C322 and 27C160 eproms. There isn't anything in the instructions on how to do it nor is there anything in the software that helps.

The three jumper wires are for the address line A19,A20,A21. Just connect those address line from adapter's address pin header to main programmer's address pin header.

See: for the main pin header on the programmer board.

The DIP switch and the jumper setting need to confirmed with software indication when you selected the chip type from the software.

Sorry to dig up an old topic, but I am having the same issue. I have a willem pcb3, and I bought an sivava adapter of ebay ( )

I set the jumpers according to willems software, and I get errors as soon as I started programming every time =(

If programming fail on random location, the your PCB3B does not work well on M27C800, M27C160 and M27C322. This is common issue on all PCB3B.
