Audio doesn't work, but here's an emulator link

https://parkertomatoes.github.io/v86/?type=com&content=aACgB...

The sound works in DosBox-X if you use the providesd config file

It also works on real old DOS PCs (or Windows XP/98 "DOS") but it would require changing a few bytes, mainly to setup UART MIDI mode

Thanks! Interestingly, I can hear noise (not music) on localhost, but not on GitHub pages. Maybe Chrome has a remote host restriction?

I remember copying logo programs from a whiteboard into an Apple II as a grade schooler. It's a great "instant results" way to introduce kids to programming, and it lends itself to exploration in a way that today's copycats ($10/mo iPad subscriptions and visio diagrams to make a character walk around) don't.

Thanks! Your project is amazing to test with just a browser. Just I've made a link using the newest version of bootLogo (now supporting procedures!)

In this particular case, FreeBasic was written in Visual BASIC for DOS 1.0 until it could compile itself. But you're right that some of the original syntax it's added (e.g. C-style pointers) takes it a bit away from what BASIC was.

All nostalgia aside, TIL that superfans reverse engineered "Space Cadet" from binary code [1] the same way they did Mario 64 [2]. Not only that, they've ported the result to use SDL and execute in the browser under Emscripten. A super-impressive technical accomplishment with a beautifully tangible result, wow!

My favorite bit - the reverse engineering process seems to have fixed the 64-bit bug Raymond Chen blogged about [3]

I was hoping they would test chip bags, because it was a plot device in the most recent Terminator movie.

After searching, I found that Kaspersky has a blog post on the topic: https://usa.kaspersky.com/blog/terminator-dark-fate-chips/18...

It surprised me that chip bags were more effective in their test than cookie tins, but only when they double-bagged it

Also used in the, IMHO, underappreciated film Enemy of the State (1998).

truck drivers used them too to avoid tracking from their employer

Try it out in a browser emulator: https://parkertomatoes.github.io/v86/?type=mbr&content=6h54U...

Awesome!

I got this:

> The string contains invalid characters.

Works for me on Firefox 60.9.0esr. No sound though.

Thanks for reporting! What's your browser? I've only tested with a recent Firefox and Chrome on Windows. I know iOS doesn't work but I don't have a means to debug it.

Otter Browser provides an up-to-date Webkit (i.e. not Blink/Chromium) engine on Windows, that replicated a lot of Safari-only bugs for me in the past.

Thanks for the recommendation!

Same here with Safari 12.1.2 on MacOS 10.14.6, just FYI.

I’m using Safari on iOS 13.2. I can help debug I’d you’d like, but I’m no expert ;)

Same here, iOS 12.4.1 Safari
