Manual + schematics = working double-size chars and smooth scroll:

Cyrillic glyphs aren't very polished, though, compared with vt240-clone (mc7105).

I've submitted a skeleton of agat7 driver (https://github.com/mamedev/mame/pull/2146) -- lots to do until it's final, but many games already work:

Heh. 48K Apple II games could pretty much be mechanically ported to anything with a 6502 and an agreeable memory map.

Here's another find (from http://agatcomp.ru/Pravetz/SuperGames.shtml) -- apple2-based arcade board (fits inside the CRT case) with Mario translation patch

Not in MAME (yet :))

Some intro screens while I work on (= copy and paste R.Belmont's code smile ) on apple2 video mode. There are all business apps (spreadsheets, databases &c). Most of the time apps don't run further than that...
