Keybard repair help. Older terminals

I suspect the most common machine to have that keyboard is either the TI99/4a or the HP85. I wouldn't suggest raiding either one for keyboard parts, but if you could find an HP85 where several of the custom chips have failed, it could be a sourve (mind you if you know of such a machine, I'd want the entire keyboard to make a keyboard for my 9915. It's electrically rhe same matric, just in a keyboard-only box, if you see what I mean, so an HP85 keybaord could be wired up). I wish. I have the HP part number for it somewhere, but the Agilent partsfinder had never heard of it. I asusme it's a rod with a couple of carefully-designed slots in the end. You put the contacts into the slots and ues the tool to push them ionto the keyboard frame and PCB. Then solder them. If you don't have the tool, it's possible to grip the contacts carefully in long-nose pliers and wrok them, a bit at a time, into place. You then have to re-form th top edge of the contat. -tony
