I currently have a Keypro FK-9000, which I bought new in 1994. The LCD display on the calculator no longer works, but everything else does. However, some of the keys stick and they repeat the character. I have tried lots of tricks and delays to fix it, but it is still an issue.
These keys can be partially disassembled for cleaning. But I don't want to start taking any apart without spares.
So does anyone have a KeyPro FK-9000 for sale? Doesn't have to function, because I want to experiment dissembling the keys, etc.
If you have one, let me know and I'll send you a Message.
