Well I don't have an HP65, I only have an HP67
which still works.
Why does the fact that an old HP calcultor still works not suprise me? :-)
My HP65 (an easy one, 13xx serial number) is fine. So are both my 67s.
OK, the've needed new card reader rollers, but that's all. And yes, I do
still _use_ them for calculations...
