HP assembly part numbers tend to be 2 groups of 5

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.
