Cardreader HP67, 4 Switches 3 Contacts?
Many thanks for the hardly wellcome!
This is my first thread in this forum. I am working on my 1997 HP76 Cardreader. According to the 4 contact fingers aktuated by the nylon-balls i only find 3 signals on the card reader control-IC: 1. Card at reader head (HDS) 2. Card reader motor switch (MTRS) 3. Card reader write protect switch (CPS) What is the 4. contact used for? Regards from Hamburg/Germany Torsten |
