But, save Confucianism, aren't they all fictions?

Or the functionality?We used to have a 5" monitor on a slightly dodgy stand with a numeric keypad underneath on one of our early ICP mass spectrometers. The MD was a fan of Star Trek and it was meant to look a bit like the thing that Spock used to stare into in the original series. It showed the mass spectrum building up in real time as the machine scanned. Graphics were handled by a TMS9929 video controller which had hardware sprites. It didn't last long like that as people often knocked it over and spilled chemicals into the keyboard. It soon ended up in the 19" racking with just arrow keys and behind a waterproof membrane.> This is similar to the MAME mindset -- do you want to *play* > the game?

First imitations of them appear in the movie 2001 when they are eating at the table. He called it astonishingly close to what we have now (or rather our designers implemented what Clarke and Kubrick had imagined back then).

It's one of those things where "exact" doesn't matter; folks either recognize the reference, or not. But, I'm having problems getting the same red "glow" (of course, the prop didn't have to actually function as a camera so higher hurdle, in my case)>> And, even a "faithful replica" is silly -- the lens used is >> wicked expensive!

And, wouldn't be as relevant, here. I have several of these scattered around the house: <https://www.ebay.com/itm/133822490002> <https://www.ebay.com/itm/143882047344> <https://www.ebay.com/itm/313626040533> <https://www.ebay.com/itm/185032320926> Their mouths and eyes are animated. Originally, I used them as speaker phones (animating their movements based on the speech from the called party). I changed that to just be "user I/O devices" (like Alexa) in my current project. Now trying to put cameras in them so they can assist with tracking occupants. I also have several of these: <https://www.ebay.com/itm/403118134325> (representative sample as they are all different) that I would like to similarly deploy. Smaller so less space wasted. But, less interesting. (and, harder to cram the electronics into!) I'd also like to have one of these (coffee table piece). But would have to make it, myself. The appeal being its more obscure reference. <http://photos1.blogger.com/x/blogger/7148/4067/1600/808171/mouse12.jpg>>>> I expect the CRT in the commercial device uses magnetic deflection, and >>> looks like they shield the crap out of it. >>> >>> A round CRT would give an even better Cold War bunker-aesthetic >> >> You could repurpose the display out of an old 'scope and drive it with >> a raster. > > Some old scopes could do that as a side show. > ie.

As a preteen, I recall viewing SSTV on a 'scope in a family friend's ham shack. It took a bit of imagination to appreciate the technology!
