This weekend I acquired an HP-97 calculator dating from 1967! It
includes a thermal printer and mag card reader.
When I got it home I found that it rattled, so I dismantled it and found
two large burnt out resistors on the keyboard PCB. The rattle was caused
by pieces of these resistors in the case.
Does anyone have docs sufficient to determine the replacement parts for
What is the power input requirements for the HP-97?
