just recently began to reinvigorate my HP 41 system, contemplating moving many programs to mass storage and emulation. a key component is my 82153A optical wand which was bought used several years ago. at best, it seems to work only intermittently now, and will not entirely scan even a short program. just changed the batteries.
i know that wiggling the connector seems to help, but not enough. are there better ways to clean the connectors? have others experienced this problem with the wand?
i almost always get wand light, but frequently cannot list CAT 2 successfully.
suggestions appreciated.
regards
