Portrait displays are quite unusual in vintage gear, and I'm curious
to learn about any examples.
Have you heard of the Facit "Twist"?
Facit was, I believe, a Swedish company, made calculators, paper tape
punches... some other miscellany, and this excellent terminal.
The terminal when seen from the side was shaped like an L, with the CRT
tube itself standing (in a plastic casing, of course) on the vertical
part of it. You could grab the CRT and twist it 90 degrees. The terminal
would send an escape code to the system, and the system would redraw the
screen with the altered aspect ratio. It was an early terminal to use a
white phosphor, and I believe it was scanned at 65Hz.
On Tuesday I'm going to a museum which has one of these...somewhere... -
I can try to get a picture of it, if you like. Norsk Data computers
supported them natively in the USER-ENVIRONMENT and NOTIS office
package.
A friend of mine who spent time around the "Studio 54" (Named after the
serial number of the NORD-10 they had been given) computer science
student group at the University, walked in and saw two fellow students
hacking away using a brand new Facit Twist donated to them by Norsk
Data.
"Oh, neat, a Twist!", he exclaimed, and immediately walked over and
rotated the CRT. Unfortunately, they were in the kernel debugger, a
decidedly non-screen-oriented program - the terminal sent its escape
code, and (IIRC) the machine immediately crashed.
