Look for inconsistencies in voltages and pulses to and

need RAM at the lowest memory locations to boot. Hooking up the keyboard
at least to eliminate a missing keyboard as a reason the system does not
boot, and you can issue commands to search a disk drive even if the display
is faulty. At least if you have a IEEE drive attached you can watch for
the the drive to respond when the 4032 is powered on, for signs of life
from the computer.
I can try that, though there may be similar bitrot in my drives since
they've not been powered up for 10+ years...
