Hi,

Does anybody know what type of system matrix board would work on a Global Warfare machine?  I had a repairman out here a few minutes ago, trying to fix the game's problems.  I replaced the EPROM chips several weeks ago, but that did not fix the issues.  He thinks the problem is related to the system matrix board.  Thanks for any assistance you can offer!

Thank you, Brian.

The repairman called it the system matrix board.  I have someone with just a little more knowledge on Game Plan games coming here soon.

I stand corrected the Global warfare is a beast. I checked with someone who ownes one ( Thenks Jeremy) this machine has a GDU board, 2 SDU boards, 1 LDU board, 1 MPU, and 1 MSU. According to Jeremy it even has what looks like a self diagnosing Power supply that has LEDs on it. Jim is a great guy. Jim post those pictures  wink

I talked with Jim this morning.  He isn't coming out here now, but he has an open invitation to stop by and see it whenever he's in the area.  I have some pictures at http://s214.photobucket.com/albums/cc88/ohiomathtchr/Global%20Warfare%20Pinball/ and can easily add more.

My next step is doing what you and Jim have both suggested--clean the connections between the backbox and the cabinet, and file down or clean the male ends a smidgen.  That is my project for later this week.

Thanks for the suggestion of cleaning the connections.  I used a toothbrush, a drill bit, and some rubbing alcohol on all the connections.  Every light is not lighting up, and quite brightly.  Some of the "logic" issues appear to be fixed.  There are some issues left--kickback targets not kicking back, bumpers not responding--but the machine is in a much more playable shape than when I got it.  I might clean the connections more this weekend, to see if that might fix anything (doubtful, but I'm up for any fix right now).  Otherwise, I might give Jim a call and see if some of his magic can make this machine work.
