Hello all,
I am working on repairing an old HP 97 calculator for a friend (date codes on the ICs are from 1977 in this one, making it a very early HP 97). This is a desktop calculator with a printer and magnetic strip reader for writing and saving programs.
I have run into a snag in that the ribbon cable that goes from the program strip reader to the circuit board has separated itself and is damaged beyond use. I attempted to save it with double-sided tape but it was of no use.
Does anyone know of a suggestion for a replacement? Originality is not an extreme concern to the owner, so replacing the connectors would be fine if needed.
The original cable has 13 conductors and is about 2.5" long. There is one row with 13 connections. All connections are straight through.
So far the best I cam come up with is making a custom cable and replacing the connections on the PCBs with regular pin headers. Problem is that I can't seem to find a 13-pin header in mass production. I did find some 26-pin (13x2) connectors and considered using them, but wanted to ask for other opinions before ordering the parts.
Thank you!
