HP-97 service manual
Hi everyone,
I have a copy of the HP-97 service manual from the DVD, but the oscilloscope printout at pages
4-24 are unreadable.
Does anyone have those pages, it'a about the card reader, with those images readable ?
Thank you very much, Alberto

RE: HP-97 service manual
Have you looked to see if the HP-67 Service Manual has better images as it’s an HP-97 minus the desktop printer so card reader schematics will be the same?

If you give me a few days, I may be able to reproduce them.

Just thinking behind my fingers :-)

The last reply I gave for your HP-65 thread gives a clue as to the expected waveform.

I uploaded a manual with clearer oscilloscope pictures (except for card read write which I will do when I can)

Thank you very much Tony, amazing work !
Can wait to see the ones about the card reader,
I have done some tests on my HP65s and I will post now some waves captured.
Hope it can help someone in trouble shooting the unit
take care Alberto

Hi all,

I uploaded another 97 service manual now with clearer card read/write oscilloscope pictures, which completes the set.
