RE: Hp-41C card reader - dead
When it comes to HP 82104A normally I go from the motor side to replace the drive wheel. This way I don't come in touch with the forks. The forks are a devil's toy ...
There is at least when more thread on the forks topic. See here: https://www.hpmuseum.org/cgi-sys/cgiwrap...ead=165472 Look at the embedded pictures (they are still hosted - most of them) If you trace back where the contacts go to you that the forks close you can measure they really close with a DMM when the contact PCB is assembled. Good luck |
