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.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.
