Last year I created an LK201 keyboard emulator that uses a USB keyboard.
More recently I extended that work to create a second one that uses a PS-2
keyboard instead. Partly because I had one and figured it would be fun to try.
You can find both designs on Github at https://github.com/pkoning2/lk201emu . The
"doc" directory describes both; in particular, file doc/kicad.md talks about
the hardware design, with pointers to an OSHPark layout, a parts BOM, and assembly
instructions.
The new one is slightly larger than the old (2 by 2 inches, rather than 2 by
1.5). I like the audio implementation a bit better; perhaps I'll revise the
USB version to use that same technique.
Enjoy. Comments and feedback will be much appreciated, either by email or on this list
or as "issues" on Github.

Unicomp is still around, so you buy a real 'Clicky Keyboard'. USB or PS2.
