DreamOS: Operating system written in Scheme

[Eduardo Cavazos]

Hello,

Dream is an R4RS Scheme interpreter written in assembly language by
David Joseph Stith:

http://www.stripedgazelle.org/joey/dream.html

He wrote a small operating system based on Dream:

http://www.stripedgazelle.org/joey/dreamos.html

I was able to boot it using 'bochs'. Once booted I "mounted" the
floppy and was able to list the files on there. It comes with a vi-
like text editor. Here's a screenshot of DreamOS running in bochs.
I've got the editor open on the svga driver:

Recompiling the OS is as simple as:

dream make_image.scm

There's also an SVGA mode available.

Both Dream and DreamOS look to be under active development; sources of
both were updated just a few days ago.

Very cool project...

Ed

Agreed! :)

It's also amazing how many projects still use R4RS. Looks like it was
damn good for the time and still sounds like pure minimalist Scheme
glory.

[gavino_learning]

when will it run firefox? on a amd64 pc?

[dmyt...@gmail.com]

Is it still alive? I think it's a truly amazing project and it's very sad the link is not valid anymore (I have a copy of the source on my hard drive though). Also, I've been trying to find more mentions about it on the internet and have not found anything.

Anyone have a copy of the latest (~2012) Dream interpreter? Wayback Machine archived the OS, but the interpreter (even all the old ones) just give me zero-byte empty tarballs or an HTTP redirection. I'd really like to see what I can do with this? Anything?
