No, I don;t think so.
HP component part numbers are off the form xxxx-xxxx (2 4-digit
groups)
where the first group essentially gives the type of component (1820 ==
digitial IC, 1826 == linear IC, 1853 == PNP transistor, 1854 == NPN
transistor, 9100 == transformer, etc).
HP subassembly part numbers are of the form xxxxx-xxxxx (2 5 digit
groups), where the first group is the model number of the
instrument/option where it was first used. For example, the CPU
control
board in an HP98x0 machine is an 09810-66513. It was first used in the
HP9810 (and was also used in the 9820, 9830 and 9821).
The fact that most HP transformers have 9100-zzzz numbers doesn't mean
they were all used in the HP9100 calculator.
Understood. I've had a few HP 5061 cesium beam oscillators over
the years, and their subassemblies are usually labeled 05061-xxxxx; I
must've missed the 4-digit vs. 5-digit distinction.

I was going through a box of old stuff and ran across
something I've
ever seen before - a 48-pin 0.156" Cinch connector w/cable hood.
From
my Commodore days, I've seen lots of 6 and 12 and 44-pin connectors,
but not 48. One telling thing is in fine print on the documentation
is the legend "HP Part No 5060-8339". It suggests to me that it
might
be useful for something in the HP1000 or HP2000 era, if I remember
anything about the innards.
Doesn't that part number suggest that it might have been used in
the HP 5060 cesium beam oscillator?
