need some info or help. Just picked up a upright race drivin. worked fine. then it froze. now it stops at downloading dsp and downloading esp. Not sure what is going on. Self test says bad rom at 200. Please help me if you have any easy way to fix. Also says brake out of calibration. thanks sam
 
battery is dead so it needs calibration every time you turn it on. Look for replacement timekeeper and you will fine one. Brake will say it does not work, but it will work. If you recalibrate it after about 5min- 10 min on, it will say it ok.

I would check voltages and maybe reseat chips.

Nice score on getting it. Looked pretty good and for $100 you can't go wrong..

Hey Sam, congrats on the pickup. I looked at that too but didn't have room for it so I didn't even try. Didn't he have some other games in the background on his ad too? Was he selling anything else?
 
you need a new 48t02 timekeeper ram, and a 48z02 nvram. Mouser has them both. They're on the main pcb.
As far as a bad rom, you should be able to locate it on the main pcb. www.hobbyroms.com can burn you new ones if needed.

I might have the drag race pcb, but thats about it..

here is info on the battery...

I have an extra set of both chips. But they are original, so your better off going with fresh batteries..

The not loading the game should have nothing to do with the battery chips. So you need to fix that problem first.. SO if you have a meter, check to see if you have proper voltages. then try to reseat the chips..

Yeah, the CC is the one I was interested in but he didn't respond to my inquiry so I'm thinking it wasn't for sale really.
