Commodore 64 PLA replacement
Commodore 64 PLA replacement
This project is an SMD version of the awesome Commodore 64 PLA -replacement by Daniel Mantione. Published under permission from Daniel.
This version uses 2 pieces of GAL20V8B chips in 28-pin PLCC package. Due to size constraints, soldering the chips is best done by hot air or hot plate, either using solder paste or tinning the pads and using flux. Fuse map is the same as in DIP-version. In the middle of the board there is a footprint for 0603 (optional) bypass capacitor, 0.1-0.22uF.
The version using DIP-chips can be found here: https://www.pcbway.com/project/shareproject/Commodore_64_PLA_replacement.html
More information, and Fuse-maps can be found from Daniel's website: http://www.freepascal.org/~daniel/c64pla/
