This PLA chip (PLS100N / 82S100) is a NOS (New Old Stock) drop in replacement for your Commodore’s 251641-2 PLA.
The chip was made by Philips and is identical to the PLA’s that Commodore produced. I get these chips as blanks and then program them with a reverse engineered dump from an original PLA. This is as close to the original Commodore PLA chip that you can get and unlike the originals which so often die, these are better designed and will last much longer.
Each chip is programmed and 100% tested.
Works on all Commodore’s that use the 251641-2 PLA chips.
Note: You will receive a variant from the chips in the product gallery. There are various Signetics PLS100N’s as well as a Phillips branded PLS100N and then some 82S100’s from Russia. They all work the same and are all quality components.
