I had not expected to open a cupboard and find this. Unfortunately it is well wedged in, so I can’t judge its state until I clear all the surrounding guff 🤦‍♂️ #retrocomputing #RetroHowOnEarthDidThatAppear

It is very pretty. Look, it even has the Christmas screensaver still running! Someone has chopped off the plug, which is just as well, as it is a 115V model (were they all?)

Someone had become frustrated at not being able to open the case and has drilled the tops off the bolts that secured the front of the clam shell, under the keyboard, so the top swings up fairly easily on the rear hinges to reveal a Ball TVX-12 CRT.

The circuit board itself is a sea of 74 series TTL, with the exception of the AY-3-1015D DUART.

@hisdeedsaredust We had them cranked to the full 19200 at uni. We also had 300 baud teletypes in that lab, with a physical bell for all those Ctrl-Gs people would send you.
