RE: fighting with a HP41c
As it is a tall key 41c I assume made in USA.
So there should be the golden balls at the tunnel to the battery pack.
Did you check the connection from the IO block to these balls?
Outer left to upper ball 0 ohm, outer right + of DMM and lower ball - about 1000 ohm.
If not there is a contact problem between IO block and keyboard PCB.
Wish you success
Andi
