I hope somebody can help me out with this. I have a 1984 Apple IIc with a Fingerprint card. The motherboard was replaced last year. The problem is sometimes, when I turn on the power, the disk drive makes a high pitched screech. Other symptoms are garbage on the screen, flickering power and disk use lights. Unfortuneately, this spectacular display of light and sound has the habbit of writting over tracks 0-2! And of course this is an intermittent problem. It first occurred about four years ago, after which I proptly had it in for service. They could not find anything wrong with it. Therefore, they decided they would replace the whole drive, just to be safe. The $360 they estimated was too expensive for a lack of a better idea. It didn't occur again until I came here to college. The interesting thing was that it died after booting up, when my foot touched the power supply (yes, I have a surge protector). It has been acting up quite a bit lately. I had an EE check out the power supply, and he said it was just fine. Has anybody ever had a similar experience, or ever heard of it ? I would really appreciate any suggestions/conjecture. Thanks in advance!

In-Reply-To: message from jgieske@polyslo.CalPoly.EDU Well.... It could be a falty wire iun your power supply. Or where you're staying's voltage or wiring could have some effect on your system. Old wiring messes up computers with lower resitance to that sorta thing (your ][c). Try buying a lone noise filter, it might help. Good luck! ----------------------------------------------------------------------- ProLine: Noahm@pro-freedom | "I only try to make the same Internet: Noahm@pro-freedom.cts.com | mistake a dozen times," UUCP: clark!pro-freedom!noahm | --Skeeve, Mything Persons, ARPA: clark!pro-freedom!noahm@nosc.mil | /\Robert Asprin/\ ------------------------------------------------------------------------
