Interesting. Trinity works fine under ZEMU.
So ZIP must be rather a hog...
V8 games that I've played under ZEMU:
BALLERINA
DREAMHOLDER
HEROINE
VIOLET

Although the party is Elvis-themed, it's really about boardgaming and
classic videogaming.
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.
Turns out there wasn't really one, so I ported the venerable ZIP (which
I have renamed "zterp" for obvious reasons) to 2.11BSD on the PDP-11,
and I also wrote a little utility I call "tmenu" to take a directory
(and an optional command applying to files in the directory) and make a
numbered menu, so that my guests who are not familiar with Actual Bourne
Shell can play games too.
These things are at:
https://github.com/athornton/pdp11-zterp
and
https://github.com/athornton/pdp11-tmenu/
Both are K&R C, and compile with the 2.11BSD system C compiler.
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. Other than that, V5 and below seem
to work mostly fine; V8 is in theory supported but no game that I've
tried has little enough low memory that I can malloc() it using C on
2.11BSD.
