Beregnyei Balazs (family name first!) derived a schematic from his die photo and wrote up notes on the circuits.

The chip is an R6502 which is a Rockwell part but uses MOS Technology's masks.

Henry S. Courbis worked with a friend of Balazs on an English translation

Balazs gave a 40 minute presentation on the reverse engineering at Hacktivity 2011, see here (original Hungarian) and here (English voiceover).
