OK so I'm working on this Rev-0 board and I think it was modified for PAL. I don't own a euro system so I have nothing to compare it to. I removed a whole load of jumpers and other crap on the back and repaired some cut traces. I got weird video out of it, so I checked the crystal and it was an M-TRON 14.25045 MHz which is wrong for NTSC.
I replaced it with a spare no-name 14.31818Mhz crystal but still messed up video....
I know the Apple II can be finicky to the brand of crystal. Since the one Mike Willegal spec'd out for his replica is no longer available, has anyone found another brand of current crystals that are know to work before I do more troubleshooting.
