Ok, perhaps I have enough information to be dangerous... On the CPU board of an Atari System 2 there are test 'holes' for +15vdc and -15vdc, having some telco experience when I measured 30vdc across both pins I assumed that to be correct since the delta between -15 and +15 is 30.
After digging on this forum and reading about the AR-II as a source of problems / power I have to ask should I get 30vdc across these two points or 15vdc and my knowledge of negative power to return does not apply here?
I have a Super Sprint that powered up fine until I fixed the monitor, now Murphy won't let me play it.
The manual list the operating temperature well above that of my garage at the moment... but I brought the 2 PCB's inside over night, the AR-II has remained in the cabinet and it would still not power up.
I examined the PCBs for trace gouges, I did notice some soldered trace wires from chip to chip, some to cut legs, I don't have another board set to reference.
Any help would be appreciated.
