[Leica] Some PDP-1 Phtos

[abridge683 at fastmail.com (Adam Bridge)]

That?s pretty terrific, Herb! Thank you.

So many ?features? of that control panel that were carried forward through 
various DEC designs (until the VAX). Now I?m going to have to look up the 
PDP-1 instruction set! My Apple Watch could probably run a PDP-1 emulator 
faster than the original! <grin> Certainly my iPhone can.

Great stuff.
