Back in the day, before the internet, you had terminal emulation. What was the most common emulation required? VT-100. Well here is an actual VT-100 terminal. The VT-102 expanded version. The VT-100 series terminals were introduced in 1978 and replaced by the VT200 series in 1983. The basic form of communications would be a terminal attached to a modem calling to a remote system or a local terminal directly attached to a system. The VT-100 worked with either RS-232 or current loop interfaces. It was one of the first to support ANSI codes and of course it set the standard for text screens.
This sample I have had for quite a few years (8 or 10). A fellow collector of antique computers had won an eBay auction for it. The problem was he was in Spain and it was in the US. He could not afford to ship it to Spain. So he had it shipped to me and I told him I would send it to him when he got the money. We exchanged email a few times and then he lost interest. Found other hobbies I suppose.
I decided to show what it would be like to use the internet with a terminal In a way I did. For some reason, I was having connection issues and kept getting the dreaded "NO CARRIER" message. I am sure it is in my init string for the modem. I suppose tech support at my ISP will be of no use. "you are trying to connect with what?!?!?!?"
