History and other comments
I actually have two SUN 3/60 computers, but I only show one here because
the PSU in my first one is broken. The second one was imported from Germany
and is in working condition.
If I ever want to use the first one (with the broken PSU) I have to repair
the PSU or I'll try connecting a peecee PSU to the mainboard. I've tried
ther latter, but I had difficulties with getting enough current on -5V
DC. I measured the current drain to about 1.7 A, and a standard PC/AT PSU
only has a 0.5 A voltage regulator for -5V DC. I replaced the regulator with
another, a 1.5A 7905 but this was not enough. The system would work a couple
of minutes and then fail, because the regulator becomes too hot and shuts
down to protect itself from burning up.
