Unfortunately I'm not currently able to take any repair jobs since I don't
have space to work on systems currently. Any model 100 today that hasn't
had it needs:

* full recap
* through board cleaning to remove corrosion and flux residue
* replacement memory battery

your issue sounds like it's related to the -5v power supply which is
usually corrected with recap and repair of damaged traces and vias in the
power supply section.
