I acquired an IBM PS/2 Model 80 (8580-071) today
and am looking for
advice on what I should do to check it out before, during, and after
applying power for the first time.
After many comments here and elsewhere indicating that nothing should
smoke, I went ahead and powered the system on.
No smoke!
But no beep nor video output nor keyboard LED activity either. (From
known working monitor and keyboard.)
It did sound like both drives spun up without a problem.
I suspect that I'm going to need to take the thing fully apart and clean
it and re-assemble it.
I may need to end up acquiring / building the parallel port diagnostic
light (LED) adapter to see if I'm getting /anything/ out of the system
plainer or if it is truly only power to peripherals.
Thank you all for the comments. If there is interest, I'll share
pictures later.
