Intro My first visit to an exhibition of old computers. It was held on November 30th and December 1st in Zürich in the “Rote Fabrik”. Given my collection of not-so-old computers I wanted to see a collection of really old computers. PDP-11 The first thing which catched my attention was a PDP-11 emulator with frontend also simulating a Tektronix 4010 graphical terminal. It’s running on a Raspberry-PI fully emulating a PDP-11 running BSD 2.
