Today, for no reason other than proving to myself I could, I manually reverse engineered a PAL22L10 from my Street Smart board.
The PAL at location D11 was the only one on this board that was security locked so until now I couldn’t copy it.
Using the ABI to test I went through each pin individually and derived equations.
After my first attempt I thought I actually had it sorted but…..

Altogether it took quite a few hours to do so will probably not do this too often but the option is there should I need to but finally the game booted up and all the outputs on my clone match the original.
