SuperPLA is a replacement part for the Commodore PLA chips which are based on the 82S100 chip. SuperPLA does NOT add any functionality, but replaces a chip that often breaks on vintage Commodore computers. A broken PLA will keep the whole computer from working - SuperPLA is meant for repair jobs like this, but also for the C64 Reloaded MK1.

SuperPLA has been available in various versions, which are all united in the latest V4 now. Jumpers on the bottom side of the product are used to configure the board for the different target computers:

• C64 (socket U17, Assy no. 326298, 250407, 250425, 250466. Assy. no. 250469 is not supported.)
• C64 Reloaded (socket U17)
• C610 (socket U118)
• C710 (socket U118)
• 264 series: C16 (socket U16), C116 (socket U101), Plus4 (socket U19)
• 1551 Floppy Cartridge
• PET (socket UE5)

SuperPLA V4 is shipped in antistatic packing. This product is shipped without printed manual. Details can be found in the Wiki article for the SuperPLA.

Two improvements have been made compared to the previous version: SuperPLA V4 now works with the "Epyx Fastload cartridge", which was popular in the US. Further, the part is considerably smaller - only a fraction of a mm bigger than the original chip. Timing-wise, SuperPLA V4 is as close to the original as possible, and even passes the "Super Zaxxon test": This game cartridge is particularly piccy about timing and will only work if all signals are generated glitch-free.
