Try removing the wire from underneath.
Sorry for my mistake, it a rev 6 not 7Exact same sounds as in the video? Are your jp10 and jp12 traces cut? They might look open but there might be small wire connecting them. I wouldn't expect a rev7 board to have this issue exactly.
look forward your result on jumper tip.Yep, the stock PALs are the OTP kind, but I couldn't even read the PALs to verify them. TOP3000 didn't have that chip in it's repertoire I guess. I bought some GAL16V8's to test replacing them. Maybe I get lucky.
But I'm going to try your jumper tip, too.. that's cool.
