TSO is older than the 3270. It originally supported start/stop terminals and 2260.

When was the 3277 relative to TSO, Wylbur, etc.? Or was it simply for online "business" applications. I was involved in writing an application that ran on the 2260, the predecessor of the 327x. The 2260 came in several screen sizes. I believe that what we supported was 24x80, or perhaps 12x80. But there was no text editor AFAIK.

How did people use that? Did editors wrap lines, thus making it effectively 6x80? I've wondered this for literally decades but never remembered to ask!
