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). Last edited by shattered; 03/12/17 02:15 PM.

Alice in Wonderland translation patch doesn't go beyond these startup screens: +
