Hello,
I recently acquired an old HP 9821A desktop calculator. It's in good shape
cosmetically, but it has apparently had previously donated some of its
internal cards to an unknown cause. Specifically, it seems to be missing
three of the four CPU cards, and two of the three RAM cards.
A quick search of some sources suggests that some or all of the CPU cards
are identical to those in the 9810A and possibly the 9830A. I don't know
about the RAM cards, though. Obviously, the CPU and RAM cards from a 9820A
would be an exact replacement.
Any help in getting this classic beast running again will be greatly
appreciated!
Thanks,
Stan
