The problem with technological smoking guns is that, however believable to those in-the-know they may appear, it's still a human problem to convince a layperson of their gravity. For example, the same technique was used to prove corruption in Pakistan [0], but a court rejected the evidence. Whether that is because they did not understand it, or were corrupt themselves, is another question.
I'm reminded of the "Rathergate" incident that got Dan Rather fired from CBS, where they went to air with documents critical of George Bush that were clumsily faked, purporting that a typewritten document from 1973 used Times New Roman in the exact same size and spacing of Word's default settings.
I remember being astonished when I first saw images of the purported documents. I could not believe this got past anyone at CBS news, let alone Dan Rather. Did they have no memory of what manual typewriter type face looked like?
I'm surprised this article doesn't mention (to my mind) the most notable recent example of font detective work - the document(s) printed in Calibri that purportedly predated its release that were evidence in the corruption case(s) against Nawaz Sharif & family/associates.
I spent many fine hours using on of those Tek terminals. The screen didn't scroll, but just kept drawing again from the top. There was a button you'd press to clear it, but people often didn't bother doing that until the redrawing made the content incomprehensible. This was back in the day when "vi" was considered an abomination, because it wasted so much effort redrawing the screen, when the "proper" way was to do line-by line changes, with ex. Oh, the good old days.
I was somewhat confusing them with storage tubes per the wiki article title but I didn't realise the tech was still around like that in the 70s! Thought it had gone long before then.
I too was taught to use ed at university and don't consider it time wasted, but I'm well chuffed that better stuff (macs) were coming in then. I actually had the questionable good fortune to use ed on a paper teletype for an hour. Then, staring down at it, my neck cricked and I had to stop.
AIUI ed (or something simpler) on paper teletypes was what original unix might have been written on - good times!
Amusing though revelatory. I simply didn't know storage tube tech was used, and it's quite possible I walked by them without realising they weren't scan-line type CRTs. Your video was an eye opener.
Modern visions of futuristic tech are a riot. Straight green lines as wireframes on a black background. I even saw that on a tube advert a couple of years ago. The monitors were green because long-persistence phosphor happened to be that colour (though orange was available if rarely seen), straight lines because that was easier for the hardware even though curves were possible just too expensive, and green on black because early scan-line monitors distorted badly when the majority of the screen was bright.
At least three tech failings became iconic 'look of the future'. That's hilarious.
I watched the original blade runner recently and right at the start a company logo of tree is drawn slowly in green on black. I said to myself - that's done on an apple 2! It must have been impressive at the time.
Funny thing, I've recently read about a terminal system that allowed choosing between green and orange as the display colors, IIRC in runtime. Forgot now what it was, though—possibly even Bloomberg terminal (those mostly don't seem to be limited in colors, but apparently use plenty of orange text in some places).
At the time I had no idea where these two choices came from, though of course I've seen lots of green in the movies. Come to think of it, in life I'm more familiar with the idea of black-and-white displays, having used such a TV with my NES and having heard of a web designer using a b&w monitor.
Upd: from pictures, it seems Bloomberg had phosphor displays in either green or orange in the 80s (CRT, I hope), so the current orange may be a big nod to those times.
