Hi Paul,
Great to hear from you.
I asked the person who produces the ChipTester about the format the PALs are read as, and it seems it’s producing brute-forced bit dumps (in a .bin format), which I’m not sure are going to be useful. They definitely won’t contain any logic formulas. Looking at a few shows some data, but in some cases it’s just the same byte repeated over and over, which doesn’t seem promising.
It’s good to hear there’s more of these units out there.
