Amazing! I did the exact same thing, when I owned the Apple II games
but wanted to play them on a C-64 at school.
On later occasions, I transferred Infocom game images serially from an
Atari 800 to the Apple II, from the Apple II to an IBM PC, and from the
IBM PC to a Mac, but I didn't have to write any bit-banging code for any
of those. I also wrote a Turbo Pascal program on the PC to read Infocom
games from Kaypro disks.
I'd reverse-engineered the Apple II Infocom interpreter myself around
1982-1983, and based on that wrote my own in Turbo Pascal in 1985. I
should have posted it to comp.sources back then, but since Infocom was
still a going concern at the time, I was afraid they would sue me.
Unfortunately I no longer have any of the software I wrote in that era.
A friend kept a printed listing of my reverse-engineered source code for
the Apple II interpreter, so I've got a PDF of scan of it here:
