Sounds more fun than NACHOS, which is what my OS course was taught with: http://www.cs.washington.edu/homes/tom/nachos/

Uwaterloo also used NACHOS. I thought it was a great course and a way to build the foundations of an OS.

I think explicit memory management was a big part of that course though, creating virtual memory etc.

Don't forget Cleese as well: http://www.larsen-b.com/Article/14.html

http://www.unununium.org/ was an earlier attempt at this, and I think it was even self-hosting, but the site no longer even hosts their source code.

To contrast, Unununium was intended to use python to make rapid prototyping of novel userland functionality a reality. Pycorn looks like it's primarily a teaching tool. Both are cool conceptually.

does anyone know if there is one like this written in common lisp?

Ask and ye shall receive.

ha! thanks man (or gal)

How available it is today I don't know but I suppose the old LISP-machines had OSes written in LISP.

do you know if its possible to find emulators? or even the machines themselves?

thanks!

There is an emulator available as a commercial product to those few folks who have a symbolics application still running. My coworker who used to work for symbolics has a lisp machine sitting in his den. And yes, it works.

I know one written in elisp... :)

Emacs is a good editor, but you can't seriously consider it an OS -- it doesn't even have threading.

I am living in one right now and it doesn't feel like it is not.

Anyway, if DOS3.3 is an OS...

not what i meant, but i like the sentiment.
