The ADM-3A was a dumb terminal (well, it had to have had some level of screen addressibility, but was definitely not ANSI-compatible), not a computer. They were sold as kits, and about 1/3 the price of a VT-100. I remember reading somewhere that they were the first glass teletypes available to the BSD folks, and Bill Joy wrote vi purely because it allowed him to monopolize one for his own use.

Yes, in addition to the cursor movement control characters, there was a single escape sequence for moving to a specified row and column. I didn't know they were sold as kits. Did you buy a kit?
