re:Battlezone woes

Tony and Roger --

Got the BZ fixed! Turned out to be a bad Dac-08.

Thanks for the heads-up on the "current" vs. "voltage" outputs and some of
the characteristics and logic. I'm still casually learning, and never
stopped to think about that.

So, this board I got untested off ebay had the following bad items:

7805
7815
cap tied to 7805 (blown open)
am6012pc
dac-08
2 bad rams

On another note, it seems the monitor, when first powered, is a certain
screen size.. we'll say size X.

After a few mins, the screen VERTICAL size decreased to maybe X-1.5 inches
on the screen.

Also, the vectors will occasionally fade out, as if someone is fiddling
with the screen/contrast knobs.. (they aren't!)

Before I dig into the monitor, does that sound like a simple cap issue in
the HV?

Thanks

Eddie
