There was a previous much larger D connector used on things like IBM and ICL mainframes, and they had two great big latches rather than the thumbscrews. You used to see these quite a bit back in the 60s and early 70s before they died out. Can't even find a reference to them now.
I had a Unix system with miniature D connectors ( 9 pin, slightly bigger than mini HDMI). Fiddly little things to plug in when reaching around the back of a box. It had two for console and modem and 16 on a card for serial terminals.
No these were great big things and very heavy duty. There were two competing solutions with offset round pins in a D shell and blades in a rectangular shell, a little like a SCART connector. The round pin version was very popular for audio 'snakes' - the fat long bundle of cables that used to take audio signals to and from the stage to the mixing console near the back of the hall.
