Yes, what I had intended (and never got around to) was to have a piece
of clear plexiglass that was fastened at the top of the board with two
stand offs (I put holes there for this reason) and the threaded barrels
of the switches would serve to secure the bottom end of the plexiglass.
The overlays could then be made of mylar (or other suitable film) on
which the overlay could be printed and attached to the plexiglass.

You forgot the 11/20, 11/45 (and it's ilk) and the 11/70. There are a
few other devices that use it as well, I just don't remember them all at

I'm working on that now. I'll include the exact parts list in a day or
so, but this gives you the gist of it:
* 2 0.01 disk caps
* 1 330uf electrolytic
* 4 ULN2308A transitor driver array
* 1 SN7400N
* 1 SN7406N
* 28 330ohm 1/4 watt resistor
* 5 1kohm 1/8 watt resistor
* 3 SPDT toggle switches (I'll get the specific p/n as the board
is designed for them to "just fit").
* 1 SPDT momentary switch (same family as above)
* 28 5mm LEDs

The ULN2308A and the switches are the only "interesting" parts. But
I've made sure that the parts can be sourced from at least one of the
