Inspired by the 45th anniversary of the IBM PC, I got my slopmachine cracking on a port of DONKEY.BAS to work in a browser. Pretty happy with the result. As a young person I remember being fascinated that you could make a game like this with so little code.

On my machine, it is flickering like _crazy_, as if it's trying to shift back and forth between two resolutions.

OSX, Firefox, browser size 3326×2830 pixels. Only happens at or around that particular size - resizing the window fixes the issue.

my car keeps hitting the donkey when switching lanes even though I'm already well past it..

Nice job. The sound effects are a bit too advanced because early IBM computers shipped with pretty simple, magnetically driven dynamic speakers.

On a related note, I’ve actually spent the last four months working on a 100% faithful adaptation of both QBasic and QuickBasic 4.5 that runs entirely in the browser on a virtual CPU and hardware abstraction layer. It’s a love letter to everyone who learned to program on Microsoft’s BASIC interpreters in the ’80s and early ’90s.

The best compliment I’ve received so far is from friends who grew up in the same era I did: when I fullscreen the browser, a few of them assumed it was a virtual machine running the real thing.

A QBasic port of the original BASIC-based DONKEY.BAS was one of the first programs I got running in it:

Ahhh I never saw donkey.bas, and only saw the Microsoft one. You know, when that company cared about being part of the industry, as opposed to being the entire industry, and really want to be 5 other industries to, as they do now.

Gorillas.bas (it's more or less like worms, except with only 1 gorilla per team)

On the plus side: it was much prettier.

It says something about what a thoughtful development environment these early BASICs were, that you could make a full simple little game like this in only 131 lines even though they're ostensibly far less powerful than modern languages. I'm not sure if you could even get an SDL window open and game loop running in 131 lines of (non-golfed) C.

Never mind how compact, beginner-friendly, and just plain fun they were to use. It's been said countless times but I'll say it again - we've lost something over the years.

Brings back memories of GORILLA.BAS! https://en.wikipedia.org/wiki/Gorillas_(video_game)

Someone gave my grandfather a Games BASICA floppy that had this and other games on it. But this copy had a few games that had been "modified". I remember in DONKEY.BAS, it would curse at you if you hit the donkey. "YOU STUPID SONOFABITCH". We thought it was hilarious. My grandfather was less pleased. He took it away from us when he found out.
