Hi Forum,
I have a new patient in my workshop.
It is a IBM PS1000 Blue Lightning that I had running a couple of months ago and I wanted to play around with it again.
Somehow It doesn't seem to post, or at least it posts incredibly slow. And by incredibly I literally mean it takes several minutes to go from counting the ram to seeking the floppy disks.
And it sounds like the floppy seek is half or quarter speed of how it sounds normally, you can hear the individual stepper ticks even.
Also when I remove the ram the beep codes are also half or quarter speed. Not sure exactly.
Has anyone ever experienced that issue?
Already tried other RAM sticks and replaced the cmos battery.
Also removed the co-processor, HDD, FDD and ISA/VLB daughterboard, but it doesn't make any difference.
I'm totally stumped...
