I should have crossposted this (http://forums.bannister.org/ubbthreads.php?ubb=showflat&Number=46766#Post46766) -- I've emulated the clone keyboard, and the video board driver is mostly usable (as long as you don't press Caps Lock . It's essentially an embedded terminal -- takes power from Q-bus, keyboard input, talks to host over serial port, and outputs composite video.
The keyboard uses nearly identical protocol and scancode set as LK201 -- f.e. it ignores the keyboard mode commands (LK_CMD_MODE in http://www.netbsd.org/docs/Hardware/Machines/DEC/lk201.html) and there is an extra key to switch layout (Latin/Cyrillic).
Keyboard driver needs more work though -- bidirectional mode is missing at the moment since video board does not use it.
