Well, it seems I have my second mysterious "chip rot" victim. (The first was a monitor.)
I have a IIc that's working mostly (won't load disks and shows a few bad characters)
It's definitely behaving like faulty RAM. I held down both apples and reset..Mine's been doing various RAM patterns in the HGR screen for some time. It seems to be orderly like it's still going, but it's sure taking a while.
My actual question is... Does anyone know how long the self diagnostic should take to run on an original rev IIc?
