C8P PS help

Post by rbihler »

I just aquired an C8P OSI system. It has the 505 MB, 3 each 520 - 16K mem boards, 540 Video, Plus the 8" drive units. I have pulled the PS to go over it first before even attempting to fire the system. Although seeing the output's or lack of from the PS I fear it has some problems and hope it didn't take anything else with it.

I have enjoyed the resources available an the web and have been going over them. However I have not been able to locate information on the power supply. Doesn't look too diffecult but data would sure be nice to have !

Does anyone have a skematic for the Power supply available? Or any idea's on where to start? It appears to be a tripple supply, the 12 V side, assuming that's correct is putting out 12.9V. I am also seeing -8V on one supply and it appears the center supply (5V ??) is shorted to 12V as well.

Thanks
Ron
