Don't let anyone tell you that if a PAL isn't the registered version, that it can be easily decoded-- they can still make use of these methods. You can soon realize just how difficult this logic can be to decode, because using these techniques the PAL becomes a memory device, where the current state depends on the previous state. Not just a simple input combination = output combination.
My point was that the PAL and original 74-series chips on the Amiga 1000 daughter-board all used simple sequential logic, aside from the latches and one 4-bit counter. So there shouldn't be much statefulness on the PALs on the Rejuvenator. Obviously it's a black-box and we won't know until we try and decode it.
