I rather suspected there were at lest three versions :-)

I also have that manual. I sent it to (someone) a couple of years ago to
be scanned/copied and they disseminated a lot of copies. Your copy may well
have come from me originally. FWIW it's part of a larger manual. Each
section (such as this one) was ordered and installed in the manual

I have a section on the HP 9133A. That's one of the old style boxs.
I also have a section on the 9123. The 9123 operates the same as a 9122
but gets it's power from the HP 150-II. It may be the same as drive and
logic board as a 9122 but I don't know. However I have a couple of 9122s
and 9123s and I could open them up and compare them if necessary.
I also have a section on the 9114 but I think you have that as well.
I also have a separate manual, 'HP-82901 M/S & HP-82902 M/S Flexible
Disk Drive Service Manual", that covers the old style 5 1/4" floppy drives.
The latter have partial PSU scheamtics, you're refered to

Yeap, Same here. I found this one at a local HP dealer and talked them
into letting me make a copy. I'm sure other dealers have some of this
laying around. I wish some of the other collectors would go beat the bushes
in their area and see what they could find.
BTW I just found a note that I missed earlier. It says that the 9133D
uses the ST-225. I think the 9133H uses a ST-4(something) drive.
