Been working on a pretty rare machine here, a model 60-111. I can't seem to find much on the internet for this exact machine, but most model 60 information is pretty much the same.
I am having problems making the machine post. The machine itself was received in a pretty sad state, so could not test it as it was. Cleaned everything up, checked every solder joint. Cleaned off any traces of corrosion etc. No matter what I do the machine will not post. I am a little out of my ballpark here, not having much experience with ps/2's.
I cleaned the cpu socket as best I could, ram is clean. Machine powers up, no post, no beeps. Already reseated the eproms, even replaced 1 that was somewhat iffy looking. Copied it on my programmer and burnt a new one. Still same symptoms... Deader then a doornail... Even tried ram I know was not compatible just to try to make it give me an error code/beep pattern. Still nothing...
Any ideas? Normally I pull out the isa diag card, but this machine is MCA...
Could it be a bad cpu or cpu socket? Only thing I can think of...
