When I tried to power up my Apple /// (built in 1980) with 256K RAM, the screen showed "memory diagnostics" and stopped there. There was a mix of 1s and 0s on it. Not sure what that means, but it doesn't look good because of the mix.
Is there documentation on how to interpret the results?
What do I need to do if it is indeed a memory error, so I'll need to find and replace those memory chips? Might be a similar problem that afflicted my old Apple II Plus where the IC connections eroded. If that is the case, or if the problem is with the memory board rather than the DRAMs, I may have to replace it?
