Can you replace your C64 PLA for under $3?

Bad PLA chips (MOS 906114-01) are a super common problem for the "breadbin" Commodore 64 machines. There are replacements around but they aren't that cheap. How about one you can build yourself at home for under $3? The GAL-PLA has been tested on longboard PCB 326298, 250407, 250425 and the SX64 with no compatibility issues or modifications required. Tested with Super Zaxxon, 1541 Ultimate II and Easy Flash 3 with no issues on both NTSC and PAL machines. 0:00 - GAL-PLA Overview 10:57 - Testing the GAL-PLA with Super Zaxxon 13:45 - How to build your own PLA 25:43 - Cost breakdown of the GAL-PLA replacement --- Video Links ** GAL-PLA Website by Daniël Mantione: (All of the information and files to build your own) ** http://www.freepascal.org/~daniel/c64...
