I think the outboard keyboard & case idea is
excellent, and a fun "hour
at a
time"kind of project to tinker with whenever
bored. :) I already took
apart one
broke >keyboard in my boneyard -- it was a membrane
type. <:-(
The keyboard was the common type similar if not the same as most
calculators of the time used. Simple XY matrix of switches and easily
replaced.
The biggest problem of the keypad is the materials didn't age well over
time. Many still
work well.
