It’s pretty simple. Each character UNIVAC can share with you is accompanied by a simple lightbulb that would shine at the right moment.
If it seems simplistic and inadequate, it was, even in 1951.
Luckily at that time, and for a few decades later, people using computers who didn’t want to look at lightbulbs or spend a lot of $ for a flickering screen, had an alternative. At that time, and for a few decades later, the best computer display was still a nearby typewriter.pic.twitter.com/bAblFDLXv7
In conclusion, if you’re interested in the history of displays, BUY MY BOOK ABOUT KEYBOARDS. But seriously, I found all of these in my research of keyboards, so I thought it’d be fun to share this parallel track!
(It’s actually a bit sad how much of this relatively recent history is already gone – how many of those specialized computers survive today only in bad scans of old newspaper photos.)
(And, if you’ve enjoyed it, you might enjoy the parallel thread called When Keyboards Were Desks: https://www.getrevue.co/profile/shift-happens/issues/when-keyboards-were-desks-190598 …)
