This is apparently a TI-77 Plus graphing and scientific calculator. So far, I've been unable to find any documentation or even marketing material on it. There's a similar calculator with an LCD that I was able to find, but nothing in this form factor with a CRT
If it went into production, this is probably the one of the thinnest, if not *the* thinnest, CRT in a non-lab setting
it is a fantasy concept from a younger 3d artist (as mentioned in the discussion they overlooked that miniature CRTs of the era had a minimum physical size so the calculator would have to be much deeper and/or the CRT angled (think of the Osborne 1, Commodore SX-64 etc)
A few of the other tells:
1) Directional Pad that's circular. Had it been in production in the 1980s they would have used a more cross-shaped one like the Nintendo.
2) The lack of any external power source. Powering a CRT off of a battery is definitely lead-acid territory, and lead-acid batteries aren't small by any measure.
@cypnk This seems too good to be true. I'd like to know more, but I'm wary that it's a well-designed image manipulation.
@craigmaloney It is indeed a concept rendering as @vfrmedia has kindly found
@cypnk They really should've used an orange plasma screen, and made it 2" thick, to pass for '90s tech.
@cypnk It’s a “fantasy concept” per https://www.reddit.com/r/RetroFuturism/comments/ovcp6y/ti77_plus_graphing_calculator_fantasy_concept/ :-)
The real one, the TI-92, had an LCD: https://en.wikipedia.org/wiki/TI-92_series
