BZ self test question

I have a Battlezone AVG that plays blind. Vector outputs show as very
distorted and almost random squiggles on scope. Fluke 9010 says that RAM is
OK and ROM sigs are correct. Flexing board, pressing on ROMs, etc makes no
difference.
Put game in selftest - gives 8 long low beeps and stops, then repeats.
Crystal changed, all connections resoldered on jumper to math board, math
board known good.
Any ideas?
Thanks
Art
