How about making a version for a REAL PDP-11/70 front panel, and one for 
a REAL PDP-11/45 front panel, for those of us who have such stashed away 
waiting for the right simulator to come along...

Electronically, it would a simple variation on the PiDP-8 (i.e., simh brains on a Raspberry Pi, hiding behind a front panel PCB). It's just a different emulator from the simh stable with less LEDs.

The switches *seem* to be feasible to produce cheaply (I will know in a month with PDP-8/I switches...). The white bezel though brings me into unknown territory. 3D CAD (based on Museum Measurements), then injection molding or vacuum forming. Or any technique to produce a plastic object in medium quantities. All I know so far is that it's very feasible - and much cheaper to do than just a few years ago.
