UK 1976 I was doing a computer science O level at the local technical college (Wednesday afternoon release from my school). There was a 19" rack modem with accoustic coupler on the front and a dial to dial the number. That was connected to a teletypewriter. We did some BASIC 'interactive' programming (the main projects used coding sheets).
The system was vulnerable to thunder storms I remember (line noise). All good fun.
