I've got a guy's Kiss pinball I've been working on for a bit.....First the quick back story...
A guy calls and tells me his Kiss pinball is resetting...and wants me to fix it. He's only had it a month or two. I go out and look at it. It's got a Two Bit repair tag hanging on it, and has seen a lot of work....a lot of non-socketed chips replaced.....massive battery damage clean-up. A lot of the IC sockets are still original (except for the lower PIA and the 5101 sockets), but they're not the crappy Scanbe brand. They seem/look OK. I check the filter cap....massive amounts of AC ripple. I change it. I also replace all the headers and connectors on the rectifier board.....they were typically burnt/hacked. She plays good...I go on my way. A few days later, he calls....it's still resetting. I decide to replace the remaining original IC sockets. On this paticular style of sockets, I pop the housing off and remove the wipers...one at a time to reduce potential damage. When I pop the housing off, I see corrosion had gotten under all the sockets. I also see someone had previously popped the socket housings off and sanded all the wipers....NICE. So, I replace all sockets, fire it back up, and play a few games. I watch the owner play a few games...as he's playing it...he goes "see, it just reset". I did see it, but it's not a traditional "reset". The game isn't re-booting. It's just kinda re-starting. The guy was on ball four. Out of the blue, he's on ball one and his score is starting over at zero. I've since seen it do this a couple more times. I haven't detected a pattern (not saying there isn't one). On random balls, and out of the blue....all of the sudden you're on ball one with the score starting over. The game never stops playing. If you were not watching the score or the ball in play displays....you wouldn't know it happened. I figured it had to be ROMs. I burned new ones...problem still happens. In desperation (the game is 25 miles away...one way) I pulled my Eight Ball Deluxe MPU, strapped it for his Kiss ROMs, and stuck it in his machine....problem still happens!!! Now I'm at a loss. The problem is totally random, and it doesn't happen a lot....maybe once every 2-3 hours. My Eight Ball Deluxe MPU has been rock solid for 7-8 years. I told the guy to really watch, and see if a pattern developes.....like if it happens only when a certain switch is hit. Honestly, I'm at a loss. Anyone, any ideas?
Thanks! Edward
