Fair enough. Sorry for the digression.

I also find myself with several flakey LK201s.
To be honest, I wouldn't be interested in replacing them with PC keyboards.
I'd prefer to get my LK201s back in action.
If the issues are in the keyswitches or the flexi-print stuff connecting them
to the electronics, it looks like it will be nearly impossible to do anything
with them.
Yes, and that is the case with mine. I know from years past that those
switches are vulnerable to contamination.
However, if it turns out that the issues are in
the electronics part of the
keyboard and they are not easily repairable for one reason or another, I may
be interested in a drop in replacement for the original electronics.
Since that wasn't my scenario I haven't tried to do that. It seems easy
enough. The main issue is that you need a controller with enough I/O lines
to run the scan. A BeagleBone would be ample; an Arduino might not be.
