Hp 65 & 67 Keyboards Message #1 Posted by Howard on 14 Apr 2005, 8:49 p.m. Does anybody know if the brass?? sheet that the keys operate on when they are pressed are interchangeable on the HP 65 & 67? I have a 65 that has lost the click on all the number keys and I have an extra 67 (the card reader is non-functional). I am thinking of changing over the brass sheet from the 67 to the 65. Any ideas???

The key contact strips, spot-welded to the PCB are the same between the 2 models. But fixing them onto the 65 PCB is decidedly non-trivial. It is possible to solder them, but IMHO the keys never feel right after doing that.
