I'm a bit far off but it sounds cool.
So I kind of wanted to put a general-purpose Z-machine
interpreter on my
PiDP-11, so that people could play Infocom (and community) games on a real
terminal.
Fun!
Turns out there wasn't really one, so I ported the

Thanks for this.
My biggest disappointment is that the memory map of
Trinity, my favorite
Infocom game, is weird and even though it's only a V5 game, I can't
allocate enough memory to start it.
Is this just a 64K segment problem? Perhaps there needs to be some
examination and optimization of the impure and pure storage and
caching design?
One can play larger games with 128K of total RAM on microcomputers,
but most of those engines are written in assembler not C so the engine
is tightly coupled to the processor architecture.
