I still can't boot OS/8 on my 8/A with RL02's. I now have the ability to download files from my PC to the console port (which goes a heck of a lot faster at 9600 baud than at 110!). For example, FOCAL-69 downloads in about 20 seconds. It works too, so I don't think the problem is with the 8/A itself. Anyhow, I have all the RL02 diagnostics from the diagpack2.rk05 image. So far, AJRLHA.BN (that's the "SEEK/FCTN" test) works without errors. I'm about to try the AJRLIA (read/write test) which should require losing the contents of a pack... What I'm looking for is a library of all the instructions for the diagnostic routines on that pack, since they are not all just "start at 0200 and follow the prompts". Is there such a thing, or do I have to try and find each one separately? At least just the AJxxxx diagnostics? thanks for any hints. -Charles
