This has too little input pins for a C64 PLA. One GAL can be used in 610 or 710 (only 8 inputs required). > Not sure how it differs from an EPROM solution, and whether it could be > adopted to other types of PLA. At least I've understood that the most > recent SuperPLA Multi has options for C64, Plus/4, 1551, C610, C710 and > 8296 UE5 so perhaps it is possible to reuse above GAL design? As I understand, the SuperPLA uses some kind of a CPLD which can perform functions similar to a GAL. Generally I this that the SuperPLA project is very nice, but it requires SMD soldering (which I can't do, and probably many people neither) and is expensive to buy (18 EUR). I am looking for something that can be easily made at home (GALs are through-hole so can be soldered easily) and for much lower price. Regards, Michau.
