Re: HP-85 power supply problem Message #11 Posted by Viktor Toth on 10 Oct 2001, 12:24 p.m., in response to message #10 by Dan M (Vermont, USA)
Dan,
Embarrassing it is to admit but... YES, that was the problem!
I did, as a matter of fact, look for on board fuses before, but I didn't see any. So I assumed that there aren't any. Since you indicated that there ARE, I looked. And looked again. And looked for a third time, and then I found it. And the fuse, of course, was blown. Thank you very much for this suggestion!
All fixed, everything works like a charm, including my freshly repaired tape drive. Now I found out that my new-old-stock tapes are all faulty. They were probably in storage for a very long time, and the oxide material came off the transparent tape at a spot, and the drive interprets this as an end-of-tape. Darn!
Viktor
