You are looking at a brand-new 100% compatible replacement PLA (Programmable Logic Array) for the Commodore 64 computer. It is built on the Philips PLS100N, which is the modern equivalent of the original Signetics 82S100 that Commodore used. These are good for all the brown "breadbin" models of C64 and the SX-64, but not with the 64C, which uses a different IC. This is as close to the 'real thing' you can get without going with a 35-year-old IC, which are prone to fai...lure.
Next to RAM, the original 906114-01 PLA (U17) is the most common IC to fail, causing black screen, garbled screen, and flashing colors. Do a Google search on the Pictorial C64 Fault Guide to see examples of common screens indicating a bad PLA.
There's a lot of PLA replacement options available today, some of them cheaper, and it's hard to know which one to choose. As a Commodore enthusiast myself, I don't want to risk anything less than 100% compatibility, so I bought a bunch for myself and others in the community. The Nu-PLA looks and performs just like an original chip, and unlike many other replacement PLAs, my Nu-PLA has no exposed header pins, so if you do have the heat shield, you don't have to bend it out of the way to avoid shorting it out.
Every one of my PLAs has been tested in a Commodore 64 computer, and especially with Epyx Fastload, Super Zaxxon, and the alternative kernal modes of EasyFlash. These are all carts that give some of the aftermarket PLAs problems, and the Nu-PLA works perfectly. Have a look at the photos that show it working with these different carts.
I have done everything I can to make sure you are getting a reliable product. Due to the nature of vintage computer repairs however, I can't guarantee that the Nu-PLA will fix your computer. There may be other things wrong with your C64, so please don't purchase expecting to return it if it turns out you bought the wrong part.
Shipping to the US and Canada only for the time being. Shipping to Canada is extra due to high shipping costs. I have friends selling in the UK, so if you're on that side of the pond, please purchase from them. Thanks for looking, and happy retro computing!
