Vintage Synth Repair

It can be something different but you should start with SCSI.

Right now somebody described similar problems with randoms resets on  
Kurzweil List, people recommended to check power supply, especially  
capacitors (big one 22000 uF in 5 V PS). And they mentioned  
possibility of corrupted OS program in PRAM. But I really don't know  
anything about it, if it's necessary to change OS chips or if OS can  
be upgraded just by loading to FlashROM. Probably such old machine  
has OS in EPROM's.

You can join this group and ask there, it's more specifically focused  
on Kurzweil gear:
