Excellent. Undocumented opcodes are one of my hobbies!
This adds one to the short list of games that I know uses them.
(Others are Bug Attack, Ms Pacman, Roundabout.)

The patch also implies the result of the illegal opcode is used.
If so, it's the only instance of that I've seen. For that reason,
and because the patch differs from the normal 6502 execution
flow, it's something worth looking into ... when there's time.

For those interested, the asimov disk image "ultima_1.dsk.gz"
is unpatched, the original bytes being:
74D1:47 43 B0 08

Cheers,
Nick.
