Astro Hacker News - Playing Zork 1 on a CP/M emulator on Linux (2021)

stevekemp |next [-]

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
     ..
     A>
     A>G:
     G>ZORK1

The emulator lives here https://github.com/skx/cpmulator

Collection of software, grouped by theme, here: https://github.com/skx/cpm-dist

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.

Reminds me of RunCPM, which also uses folders rather than disk images:

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.

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.

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!

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.

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.

Was this vibe-coded project ever actually tested?

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.

Description:

  >climb 
  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.
