WTB: Williams System 4-7 CPU board
« on: December 28, 2010, 11:44:51 AM »
Looks like the CPU board in my Williams Flash is corroded beyond repair. I've done the upgrades listed on Pin Repair, resocketed it, checked with Leon's Test ROM, etc. and still no luck. Looking to see if anyone has a reasonably priced working Williams System 4-7 CPU board. I know about the new combo boards but I'm trying to avoid $250+ to fix the game.

Really not $260 for a combo... (http://www.rottendog.us/mpu327.htm)

Figure getting something for your old stuff the ebay route, even if not working.  Someone out there has the time and inclination to buy non op stuff and get it going. 

On ebay now there's an untested clean one for $65 buy it now and rebuilds run in the $140-$160 range.

I'd guess probably $50 to $75 for both the MPU and driver board to help defray the outlay for a new one, taking your investment down to ~$180 to $200 depending.  And you'll sleep soundly at night with a new one not worrying what will go next.
