      Wait, the ADM-2 had a microcontroller? The ADM-3A didn't, did it? I didn't see one when I took mine apart, but that was a long time ago

      On page 1-2 it explains that if you send ESC U then "control characters can be displayed", not just STX and ETX.

      The ADM-2 keyboard also has many more keys than the ADM-3A. Maybe the ADM-3A was a radically-stripped-down version, nearly just a glass tty?

      Yep, I believe so – the first one to hit a $995 price point (some assembly required).

      So it seems—and apparently the "A" at the end was the addition of the minimal cursor control stuff.

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

      Amazing that it took $50 worth of hardware to do that cursor movementpic.twitter.com/dei5ZebQPn

      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

      Ah, this is lovely. I like how they call the cursor the “X-bit.”
