Hello,
Bought this board today, seemed to be in perfect shape for something built 26 years ago. But upon closer inspection I found one of the chips to be broken (split in two, as if hit with great force): it's the one labeled PAL 089-001. Removed the label, the chip is a PAL16L8BCN, which according to the datasheet is a "Programmable replacement for high-speed TTL logic". How screwed am I? Any chance of reviving this board? As it is now, with or without the broken chip, I get a series of three short beeps after power-on.
