(There is the related VT62, used with the shortest-lived operating system in history, TRAX.) The VT61/t was the entry level editing terminal for Typeset-11. It's a forms processing and text editing terminal. It uses block mode transmission in both directions, one screen at a time. I think the protocol was pretty hairy -- finding any documentation on how it worked is likely to be quite difficult. For text editing it's actually pretty pathetic, but it was cheap by comparison to the serious editing terminal, the VT71. (That one has an LSI-11 inside, and can edit a full document, up to 32kbytes or so long, all in local memory.) On the other hand, for forms entry as you would encounter it in the classified advertising department, it worked very well. Internally those terminals are monsters -- many circuit boards, all single sided etch with thousands of jumper wires on the other side to make up for that. Why they didn't use double sided boards is still a puzzle to me... paul
