I'm aware of some airborne (avionics) computers that used i960s. There
were Mil-spec versions available.
I believe the i960 really only found a niche in embedded applications.
If I recall correctly, the i960 became available at about the same time
as the 80386 but was less expensive. At the

That's a UNICHANNEL-15: it allowed devices on the -11 to do DMA directly into

It's a little switching power supply. It steps up the 9V input voltage
to something a few volts greater than 12V to feed the 12V regulator.
If your 12V is correct, it is probably working.
