I have a chance to get a FREE Battlezone, I just have to drive and pick it up. I am told the is a problem with one of the boards, but he can't remember what it is. Does anyone know some of the common issues with the unit? Thanks

I've worked on a few _Battlezone_ boardsets and here are some things I've
run across. Perhaps this can help...
*) Bad sockets. Very common problem on older Atari boards, specifically
beneath the ROMs. Can also happen underneath the 2901's on the auxiliary
board and the 6502.
*) Bad 2114 RAMs. If in doubt, replace them all. After 20 years, if one
original fails, the others probably aren't far behind. You don't want a
boardset coming back a week later.
*) Bad crystal. Sometimes it literally falls right off the board. If you
can't find the 12.096 MHz type, a 12.000 MHz should work just as well.
*) Bad solder joints on the cable connectors between the CPU board and
auxiliary board.
*) Bad PROMs on the aux board.
*) Bad 2901s on the aux board.
*) Bad video output circuitry on the CPU board. If the game plays blind,
look at the X OUT and Y OUT test points with an X/Y oscilloscope and see if
you have a bad video output. Could be just a bad op-amp. Sometimes the
adjustment pots in this area have broken legs or are missing entirely.

Sounds like a no-brainer. I have seen vectors not fire up when the cap goes bad in the bottom, too.
