After reading this section, I should probably bring up that when I checked the PSU
voltages, the 5v+ line was low, at 4.7v or so. I adjusted it back to 5.05v on the pot as
defined in the manual, and there it stayed steady, but it didn't seem to help. Before
I adjusted the pot, it was fluctuating.
Given the age of the unit, its not surprising that the potentiometers are a noisy, have
drifted/aged and/or are contaminated with crud.
SYSTEM Reset L should be High. If Not then Check for 1.1V on THR.
