I was aimlessly clicking through some Russian sites when I came across Sergei Frolov. Seems like a cool guy with his own Elektronika 60 and even his own computer museum. Looking around there it appears the BBC Documentary wasn't showing an Elektronika 60 but instead a DVK-3M or something similar to it. It's another DEC PDP-11 compatible computer so it seems reasonable enough.

Is that a new lead or am I treading old ground?
