I recently acquired a keyboard from a Greek Linotype CRTronic 360 machine
Shown here in this (probably promotional) picture with the machine itself. The Linotype CRTronic 360 was a typesetting machine.
The switches are Linear Rafi RS 76 C Hall Effect
The keycaps are shiny doubleshots
Unfortunately, the massive case has a few scuffs and scrapes
The cable and connector are equally massive, and each end of the cable has a separate ground wire. The machine-side connector has the pins labelled on the inside, and a spot of rust.
No idea what type or protocol connector is, most likely proprietary. Here is the keyboard side.
The back side of the keyboard
And a close-up of the label
Opening it we find the controller, which connects to the switch PCB with a ribbon cable
The controller
Frankly, I don't know a whole lot about this keyboard or the machine, and information seems sparse. I suppose most of them got trashed by newspaper organisations once digital printing came about, and a few are still in storage areas. If anyone has any information to add, feel free.
