I'll second that. The Model II keyboard has to be the worst
implementation I've ever seen. Not only does the foam pad disintegrate,
but it takes with it the metallic coating on the underside of the plastic
disc that presses against the circuit board. On my keyboard, a total
of FIVE keys were still working.
Based on the articles I've read about rebuilding capacitive keyboards,
I think I can resurrect it. Unfortunately, I don't have the materials on
hand. I'll see what I can dig up.
On the positive side, the 8" CP/M 2.2 boot diskette I created using IMD
worked perfectly. :-)
