Показать описание
My first real PP board repair. Use the FPGA Catbox to find bad 7C, fix some alkaline damage, and then get lucky with quick shotgun of z8002. The video is 40 min but I probably spent 15 hours screwing around with it.

Was the GAL/PAL chip bad or was the real problem because that one pin was left out of the socket causing you to think the GAL/PAL chip was bad? Do you know the GAL/PAL chip is doing like is it doing some type of RAM addressing decoding or what
