Repair Logs
Omega Race (Midway) PCB repairs
02/29/2000
Tools: chip puller :-)
Problem: High constant blaring pitch for sound.
The self-test showed "RAM 3 BAD", the manual told me that
it could be 3 different RAM chips. Swapping in a known good chip into each
location pin-pointed the RAM chip at location 3C as bad.
Solutions: Replacing bad RAM chip at location 3C fixed the sound
