OscarvWell, the front panel of a real 8/I. I can't even remember how long I wanted one. Today was a good day. An excellent day. An 8/I FP in perfect condition found its way home to me thanks to PDP collector and expert hb9aik (saying thanks once is not enough, so thank you!). Here it is, next to the PiDP replica:
This, of course, will spawn a whole new project: letting the PiDP code drive the real panel. But first, the PiDP replica needs to be finished. Risk of distraction :)

A decent scan/model of one of those beautiful PDP toggle covers would be a nice start towards getting some new ones made. I love those things! (and finding a source for suitable toggles)

You could take the SVG vector drawing from my site and overlay it on a photo from a real PDP-8/I. Then you'll see only two things need amending to make a full-sized original 8/I panel replica: (1) The bottom 'switch bar' lines needs moving a few mm and (2) the drawing needs the key lock of the original PDP-8/I added on the left-hand side of the panel. The rest is already an exact replica.
The toggles can be 3D printed. 3D models are here: http://so-much-stuff.com/pdp8/cad/3d.php

Thanks! I've never had a chance to see these things up close and personal. I'd assumed that they were push-fitted onto the switches, but it looks like there's some kind of rail they clip to. Do you have any pictures of what is happening behind one?
Are you sure? yes | no
Have a look mid-way on this page, that's my version of the rail the switches are mounted to: http://obsolescence.wix.com/obsolescence#!pidp-8-building-instructions/c19ll

Looks good! I sent you a PM. I'm very interested in purchasing one of your PDP 8/I
