There's a simpler way now, I wrote a golang based CP/M emulator which uses the local filesystem, instead of "disks".
You can clone the repository, or run the docker image, and be playing zork in minutes - I even put together a repository containing a collection of vintage CP/M software (which includes Turbo Pascal, and Zork 1, 2, & 3).
Quick start:
docker run --pull=always -t -i ghcr.io/skx/cpmulator:master
..

G>ZORK1
What is the rationale for packaging it as a container? Isn't the point of golang that you can have a static executable that just works, so you could just distribute a zip archive with the executable and software folders? Or is it to provide some degree of isolation from possibly malicious CP/M software?
The source is available, and you can "go get", and "go install" it in the standard way.
I've merely configured a docker container to be generated on every push as an optional additional installation method - that way I can paste in instructions for those who have docker available, but don't necessarily have a go compiler installed.
Use the container if you like, use the repository source in the typical way if you prefer.
That sounds like something that would be completely impossible to fix, I am sure.
It's too bad, because most modern machines only have single-core CPUs, and I've never heard of any operating system that has the ability to throttle a process by lowering its priority or reducing its timeslice. Someone should implement that, maybe calling it "process control groups" or something.
I still keep a Kaypro II hooked up in my garage mostly just to show people Zork on a tiny green display in a suitcase sized luggable computer as God intended.
This was a childhood highlight moment for me. I'd been playing Adventure for ages just having fun without realizing there was a huge world beyond the snake.
Heh. Cool. I still remember playing Zork as an undergrad in MDL running under TOPS-20 on a DECSYSTEM-2060 at NE43. So much better than hack or rogue when I was stuck on a problem.
Head north from the house, and then head north again so that you're on the path winding through the forest where there's a large tree. Climb the tree. Observe the picture which inexplicably shows you back at the house.
And not only that, it's a completely different architecture than the house shown at the beginning of the game.

Up a Tree
You are about 10 feet above the ground nestled among some large branches. The nearest branch above you is above your reach. Beside you on the branch is a small bird's nest. In the bird's nest is a large egg encrusted with precious jewels, apparently scavenged by a childless songbird. The egg is covered with fine gold inlay, and ornamented in lapis lazuli and mother-of-pearl. Unlike most eggs, this one is hinged and closed with a delicate looking clasp. The egg appears extremely fragile.

Reminds me of RunCPM, which also uses folders rather than disk images:
https://github.com/MockbaTheBorg/RunCPM/
RunCPM also provides a link to the author's CP/M software archive.
RunCPM will bog the CPU like crazy, it emulates the machine at 100% with no throttling at all.

It is pitch dark. You are likely to be eaten by a Grue.

Kill dragon
With what? Your bare hands?
Yes
Congratulations! You have just vanquished a dragon with your bare hands!

Very nice.
FWIW, frotz can be used to play these games on Linux and *BSD. See for these type games:

The article from the link above is below. You should be able to get some games from it.

The most fun thing that I do with the RC2014 computer I built is play Zork.
I played this in both ms-dos and dosbox.
We have web based AI illustrated versions now

Was this vibe-coded project ever actually tested?

I dunno.
I played a different one with AI generated graphics that was posted on here a few weeks back.
I didn't play through this one.
Although its been decades, the one I did play through seemed original.
Try "GIVE TROLL TO TROLL"!

Chuck Bartowski would be proud
Tristam Island, a Z3 game, will run fine under CP/M.
I rebuilt the full version (full texts) for old machines:
https://caja.texto-plano.xyz/anthk/zgames/eng/tristam.zip
Just rename the Z3 file to ZORK1.DAT... or try getting some 'modern' ZMachine emulator elsewhere.
