The 82 s100 like the 906114 has 28 pins (same size as SID and worst of all SId and PLA swap places between rev a and b boards so someone might by accident fry a PLA by putting it in a SID socket). --Ray >In reply to Ethan Dicks: > >> > Since some of the early C64's used the 82s100 instead of the MOS > > > 906114 can't this GAL/adapter fix work on most c64 boards (rev A-C)? > >Now, to come back to the 82S100 problem: it has 16 inputs and 8 outputs.

Take a look at the GAL26V12 from Lattice... an 28- >pin DIP package that even looks much like the 82S100. Different pinning >though. the GAL6001 would maybe even better, since it has its power pins on >the edges @ a 24-pin DIP pacakge. I can't remember though whether the 82S100 >is 24 pins or 28 pins. -- --------------------------------------------------------------- |Raymond C.
