I have a piece of test equipment with a touch pad that has delaminated and would cost $500.00 to replace. Is it possible to adapt a computer keyboard to replace the touchpad? The touchpad has a numeric keypad and a variety of function keys. The flat cable going to it has 12 wires. I have an old (new in bag) keyboard from a TI 94A (boy does that date me!) that looks like it would plug into a remote keypad plugin on the display circuit board. If the keyboard just acts as switches, couldn't I just remap the keys?
