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.
