Technical manual is rather good, and mentions a graphics option with Tek 401x and ReGIS features. Manual + schematics = working double-size chars and smooth scroll: Cyrillic glyphs aren't very polished, though, compared with vt240-clone (mc7105). When firmware thinks there is a graphics card, a Tek 4010 mode menu suddenly appears: Graphic card is rather simple -- basically a "glass plotter" (no upd7220 there, it's all discrete chips).
