Battlezone self test problem

've got a new one.

Ran fluke long and short ram tests good.
Rom signature tests come back good.
Tested aux board with good main no problem

Game coins up, plays, but graphics are all screwy.
Put in Test and get one long continuous tone before watchdog kicks in.

Manual states a long low tone will be present when Vrom B/C3 is bad.

Have swapped both Vroms, and even tried the highscore kit. Still can't get
test screen to come up.

Based on the fact the game does play, I'm guessing it's in the VSM area
somewhere.

Any pointers?
