I've got a Super Pac-Man board on the bench trying to fix this thing up. It is throwing a ROM 3 error on startup, which indicates the ROM at 1K is bad (or inaccessible). The ROM is fine, checks out OK when dumped, and the 6809 subprocessor that controls it is also confirmed good. Sockets also appear to be good.

The 6809 is stuck LOW on the reset line, which traces back to an 74LS259 at 2M. Input pin 14 of this chip is floating, which is only connected to output pin 14 of a PAL10L8 at 1M. So I'd have to say the PAL is shot.

So since I don't have any PAL10L8's, but I do have GAL16V8's....here was my plan, all while not knowing jack sh*t about JED files.

I want to download the PAL dump from JammaArcade (PAL dump SP1-2-1M), convert it to GAL format, burn the GAL16V8 and move on. However this is what I'm running into....when I decompile the PAL dump using JED2EQN, the equations do not show any usage on input pins 5 and 6. However those pins are definitely used, when probing, and according to the schematics.

So I guess what I'm asking is, can someone with more expertise with PAL dumps either confirm that I'm not decompiling and converting correctly, ... or that the dump is not usable. It is marked as "assumed working" and therefore untested, so I'm not 100% sure about it. FYI, I did convert it using PAL2GAL, and also JED2EQN->EQN2JED. Both attempts were burned to GAL, and when installed in the board, caused the 6809 reset line to be pulsing and still throwing ROM 3 error.
