Red Baron, Fix phase one

Okay, I gave up last night & swapped the RB chips into a working Battlezone
AVG board & low & behold my mathbox actually works. I'm planning to go back
& verify my signatures & see if this makes a difference.

Before I did swap I noticed that the scale of the lettering on the original
RB AVG seems to increase from left to right, top to bottom. In other words.
The "SCORE" and "VALUE" displays seem okay but "HIGH SCORE" is larger and
cut off, being only "HIGH SCO". The "ATARI" at the bottom of the screen is
also larger.

I spent a little time poking around for a bad line in the scale section but
I didn't find anything that is stuck so I'm guessing I've got a counter or
gate that hasn't completely failed?

Any suggestions for cornering that bugger?

Thanks,
Kev
