Good news: I found the complete service manual of 82901
and 82902 drives.
It
contains full schematics and detailed description of the circuit.
I'll scan it and post it asap.
Here you can download the full service manual:

It's uploading now: it'll be ready in 10 minutes (it's 37MB size). I sent it
to HPMuseum also.
Thank you.
