RE: Hp-41C card reader - dead - UPDATE
All, the new Duracell batteries have arrived. Put them in the calculator but the card reader motor doesn't move. I can CATALOG 2 the reader but inserting a card doesn't trigger anything.
I don't believe the ICs and PCBs are at fault, I wouldn't get a catalog 2 operation to work. The motor by itself works as I tested it prior to starting this project. I have noticed that the red and black cables that go to the motor are simply 'inserted' into 2 sockets located on the bottom PCB and not soldered. Suggestions on what else I can try ? Thanks Marco |
