Most early terminals were actually 80x24. I know the DEC VT series were. I remember being surprised when the IBM PC came out with an 80x25 display.

- kps 7y agoEarly video terminals had a variety of sizes. The 1964 GE Data Editing Display (earliest I can find a manual¹ for) had 46×26. The 1967 Datapoint 3300 had 72×25. The 1967 Sanders 720 had (up to) 40×50 or 64×32, depending which orientation you got the monitor. But the IBM 2260, their first character display, had 40 or 80 columns by 6 or 12 lines, depending on how much you spent on the controller, which stored a cluster of terminals' displays on acoustic delay lines. ¹ https://archive.org/details/bitsavers_geterminalayDec64_1626712 https://archive.org/details/bitsavers_geterminalayDec64_1626...
- Taniwha 7y agoYes Burroughs block mode terminals of the same era (late 70s) as the VT52s were also 80x24 - we were very much editing 80 column card images at the time
