I was going through a box of old stuff and ran

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?
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.
I've seen plenty of HP hooded card edge connectors, ceertainl in 0.125"
and 0.156" pitch (and problably 0.1" too). A common one is a 44 pin (22
pins each side) 0.125" one (very hard to find in non-HP stuff).
As regards the 0.156" ones, I've certainly seen 15 pins/side and 18
pins/side ones used in HP instrumetns. 24 pins would not suprise me.
