Not exactly a TTY story, but related by slow bit rate and antiquity....
Haven't seen a C64 terminal for years.
It was my first glass screen terminal.
I originally got just the circuit board from it when I bought my first computer, a SWTPC 6800, with 8K of memory. No keyboard or case. At the University of Nebraska, they had a few 300 baud dial-up ports to their IBM 360/370 mainframe that all the student (and administrative) work was done on. I finally dug up an ASCII keyboard (no case either), although it was parallel so I had to build up a UART circuit on a protoboard to get it to send serial. I think the C-64 was missing a few parts but got those together and found a discarded 19" screen out of an old arcade game (no case again). Finally got it all running. I think I had the C64 motherboard in a cardboard box. Probably one of the few terminals, if any, in a dorm. Sure beat walking in the snow and wind in the winter to the engineering building. Only line-mode editing on it.
Those were the days (late 70's, early 80's).
