Williams System 3 - Disco Fever - ROM failure - location?
« on: November 27, 2013, 10:55:12 AM »
i've had the CMOS chip socketed and replaced, and have a fresh burnt new game rom installed. the MPU is still indicating a ROM failure...is it 1 of the 2 (marked 2 and 3) to the left of what i circled? (game rom)

thanks.
