Badbaud, are you and Larry still in the business of keeping these Bally 5000+ alive? If so, I would love your expert advice and likely services to revive mine. Just purchased one from someone who tried in vien to revive one, and now I'm taking a shot at it. I was able to diagnose a failed power supply and jumper wire their replacement battery. In my excitement at the rebirth startup (wheels slowly spinning and self testing mode) I stupidly touched the unknown white and black striped power fail wire to the 24v side of the power supply. Now all I can get is error code 82. I've performed every RAM clear mode described on Google (actually get the read out CH/CL on the display), but still error code 82 in the end. I'm at wit's end, do I parts out this beautiful machine or is there hope for bringing it back from my mistake?
