I remember at DEC when we all at VT100’s and then the big day came when we could upgrade to the “New Color” monitors Ah just to think of the orange glow of the words radiating from the screen. Of course you could get green as well. Not a lot of choice compared to today but ground breaking at the time.
The company I used to work for still makes brand new VT’s since folks like them so much. VT520 and the DEC style keyboards. Some things never go out of style.
