I like that the ADM-3 documentation refers to "backspace" and "forespace" as opposites

It's easy to believe — have you had one apart? The combinational logic for the character processing state machine must have been a PITA

I like this so much. From IBM 2260 manual. (IBM 2260 seems like the earliest CRT terminal I can find, 1964.)pic.twitter.com/XFr1MAmVXH

The Charactron (with a perforated-anode character generator) was from 1954 and was used as the console for SAGE; Typotron was 1953

Yep, late 1960s > 1964, though. Although I’m sure there must have been a CRT keyboard terminal before IBM 2260!

I don't think SAGE's display is a "terminal"—as you say, it doesn't have a keyboard, but also it doesn't have a serial port or memory!

Back on the ADM-2, page 6-2 lists the microprogram instruction set; it looks like you could program it to do squareroots and stuff in theory
