What's the availability of replacement C64 PLAs
You can make one with an EPROM programmer and a 27512 EPROM.
You need to create two personality modules. PLA -> 27512 and 27512 -> PLA.
First plug a working PLA into the first personality module and read it in with your EPROM programmer. Then write the resulting data to the 27512. Plug the 27512 to the second personality module and then plug that combination into the C-64's motherboard.
Try and find as fast an eprom as you can.
Probably even flash memory could work.. I'll have to investigate.
