The televideo 910 wasintroduced in May, 1981 - that's very exact isn't it! 12" screen.
This one is the zombie version - dirty with bits missing. Does not power up.
It was a classic, text-based "dumb terminal" from early 1980, known for its "marshmallow" look. It connected users to mainframes, offering ADM-3A/Hazeltine 1410 emulation, multiple character sets (English, French, German, Spanish), and visual attributes (reverse video, underline, blink) at a budget-friendly price for its time.
It is now popular with hobbyists for retro computing projects.
