Re: Help: HP9825A Power Up Issue Message #4 Posted by John M (Ottawa) on 19 Sept 2012, 1:54 p.m., in response to message #1 by John M (Ottawa)
Thank you for the suggestions.
1. Steve - No stuck keys.
2. Tony - Power supplies voltages look OK. Not much ripple on the few lines I checked. (Thanks for the schematics).
Upon further experimentation, the 9825A works OK with a tape inserted in the tape drive. I was initially reluctant to insert a tape since the drive's capstan wheel is obviously gummy. But when I insert a tape, the "error 01" resets. Eject the tape - I get the error 01 when any key is pressed.
Alas, now my big decision - rebuild the tape drive or not?
