At the time (up through 1993), that was what we had. In open labs, there would be some jockeying for the better (newer, almost always) terminals -- a VT420 with white phosphor being the pinnacle of experiences, anything in amber usually being ranked lower than the same in green, except for one Wyse series I had mostly forgotten, where the green was eye-searingly bad with the brightness up, and muddy/blurry with the brightness down.

And then we had Linux on PCs and that was so much better nobody wanted to use the terminals again if they could avoid them.
