Hazeltine?

It's kind of boxy: one rectangular box for the monitor, with a black front and sort of goldenrod-shade-of-beige metal case, or maybe the ones I saw were just yellowed by exposure to chain-smoking programmers, and a matching yellowish boxy keyboard attached by way of a thick cable. The display is a relatively long-persistence green CRT, capable of showing twenty-something (24 I think) lines of 74 columns each. The ones I saw could not display lower case, but as they were talking to something whose native character set was FIELDATA there was no lower case that needed displaying. Best of all, it's too stupid to clear the screen when powered on, and likely as not what it greets you with first thing in the morning is a garbled version of what it was showing you last night when you turned it off. (There is a reset button, one of the round pushbuttons on the right edge of the keyboard, which clears the display should you like to start fresh.) So while I wouldn't be surprised to find that the display memory is core, I'd be even less surprised to find that it is some kind of acoustic delay line. I wish I had had the foresight to grab one when that PPOE got rid of them in the mid-1980s, because I haven't seen one since. I do seem to have kept a manual and my inventory says it is dated January 1975. -Frank McConnell
