Hi Alex,
Thanks for responding. I have not been able to get diagnostics to run. I was under the assumption that if the display was only showing blocks you couldn't get to diagnostics. But I have tried every combination of holding two buttons while powering on that is listed for all the different models. I guess I have two main questions right now that will help me determine how to approach my next phase of troubleshooting.
1) What jumpers should I have for the pro76 configuration? Right now I have jumpered JP2, JP3, JP18 near the eproms, JP8 and JP14 near the Arnolds, JP11 near the sound roms, and I also added JP5 near the sound roms based on info on K1000.net. I think my motherboard is one of the latest versions as it has sockets for all the sound roms.
2) Would bad Arnold chips prevent it from booting up and getting to diagnostics? If these are not needed I can ignore them for now.
