A quick comment.....
HP assembly part numbers tend to be 2 groups of 5 dgits and the first
group is the model number of the device that first used that assembly,
padded out with 0's. For example, the data path board in an HP98x0 systm
is an 09810-66514, since it was first used in the 9810 calculator.
So your boards were used in an HP7970. and maybe other models besides

I note that HP is now recycling its model numbers (I suppose that
there weren't enough numbers and letters left). The HP 7970 is also
the model number of a Pavillion desktop PeeCee.

A feww years ago I was saddened to learn than an HP9100C was some kind of
printer/scanner thingy, and nothing to do with the 9100A/9100B
calculators (which as I've said before are the most elegant pieces of
electronicvs I've ever had the pleasure to work on).
THinking about it there were _5_ calculaotrs all claiming to be a model 10...
HP9810 (aka Model 10 calculator) -- a 3 level stack RPN desktop machine
HP10 (aka HP10A) -- a printing adding machine
HP10C -- simple scientific programmable in the 'Voyager' sereis
HP10B -- Algebraic-notation bussiness calculator
HP10B-II -- improved version of the last.
