A3000 PAL chips
« on: April 18, 2003, 03:39:56 PM »
I am looking to source the U202/U203 PAL chips for an A3000D. Mine are broken resulting in graphics issues and non-working floppy.

I have the JEDEC source files of the chips from the haynie archives as well, so if some friendly soul with a PAL/GAL programmer could program chips for me as well it would be great.

I live in sweden.

Regards,
  Johan

1. What brand and model are the chips of?

It does actually not matter. I have no blanks as of yet either. I have seen several pages mention that a GAL16V8 would work equally well. The chips currently seated (non-working) are PAL16L8DCN, the only vendor markings I can find are "MMI".

2. What physical type are the chips? (DIP, PLCC etc)  
3. What are the pincount of the chips?

20 pin DIP

If you could help me I would be eternally grateful, please drop me an email.

Kind regards,
