Hello all! :)
A while back, I purchased a smoking HP85.
I'm finally getting into the fixing it stage... The part in question
looks to be a transformer labelled 9100-0457 / 906933. It has a
similar, happier cousin labelled 9100-0455 / 906933. The caps are
Where is this part in the machine? On the PSU/printer board, the video
board, or what?
You can get the HP85 'Assembly Level Service Manual' on one of the HP
Museum CD-ROMs (look at http://www.hpmuseum.org/). Despite the name, it
does include schematics, but it won't contain transformer winding
details. You may have to work out what the transformer was from the circuit.
