Hey everyone
Been along time since i worked on any pinball machine but recently scored myself a Zaccaria Time Machine pinball in pretty good nick. Saved this from going to dump as the owner didn't want it anymore nor wanted it to be repaired. Originally the machine did work but now just the lights turn on but nothing else happens. Personally never tried this machine out to see what it does but i thought would be best checking each pcb first
Anyway long story short been doing some searching seems there is a alot of info plus test rom made by Leon? tried to get into his site but can't seem to find anywhere to download this or any other info
All ive done so far is taken out the MPU removed the battery as it was had it seems PCB didnt suffer any acid damage, metered a few dark looking tracks all checked out and fired it up on the bench using just +5 volts
All the test points listed here http://www.zaccaria-pinball.com/gen2/cpu.html match what i got so i take it the MPU maybe ok
So next ill check out the power transformer and power supply PCB
Any info or help and what to look for would be great
