joshk #1 Posted October 14, 2003 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 Quote Share this post Link to post Share on other sites

McCullar ([email protected])Subject: Re: Looking for Battlezone PCB repair tips Newsgroups: rec.games.video.arcade.collecting Date: 2003-03-30 21:30:08 PST 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.

sebastius #4 Posted October 15, 2003 GET IT!!! Battlezone is worth any effort to fix it! Wish i could get such a deal. 50 euro's for it? Quote Share this post Link to post Share on other sites
chadtower #5 Posted October 15, 2003 Hell, get it for the empty cab if for nothing else. Quote Share this post Link to post Share on other sites
Cassidy Nolen #6 Posted October 15, 2003 Sounds like a no-brainer. I have seen vectors not fire up when the cap goes bad in the bottom, too. Matt knows what he is talking about. Been around a long while in this game! Cassidy Quote Share this post Link to post Share on other sites
