Nice to see this wonderful project getting love it deserves.

But what is it? The README is just a bunch of screenshots and disjointed comments about what features it has listed in no particular order. It would be great if there was some summary from a birds eye view of what the project actually is.

I think the "what" was intended to be covered by the initial flurry of contents, "MIMD, multi CPU, multi threaded, multi core, multi user Parallel OS".

Give it a try! The page includes snapshot.zip and a number of scripts to start you off. See also

Caveat: I'm not a lisp-person, however:

It looks like a modern interpretation of a Lisp machine -- a "real" Lisp, where the entire environment is a Lisp, and you can network and do GUI stuff and OS stuff in Lisp, running either in a hosted environment or maybe on bare metal eventually.

Looks like OS with Lisp all the way down

Never got it to run properly on MacOS. Seems really neat though!

I did, fairly easily. What an amazing project! I'm going to be exploring this for a long time...

Just tried again, it looks like that additional makefile for building against homebrew SDL may have done the trick.

Very interesting!

Ah yeah, I had to add to CFLAGS for SDL2.

Thanks for your interest again folks. Sorry this year has been a bit sparse on updates due to the death of my partner Aihua, and brother-in-law.

Deepest condolences; hope you're doing OK.

I missed the previous postings; this is an impressive piece of work!

Oh, I am very sorry to hear that. My condolences, and also my congratulations on a fine looking OS.

Wow! Pretty impressive. I opened a Chess game and then went into Edit to see if I could live edit Chess/app.lisp to change the title bar name to "Chess" in the running instance, but the change only shows after I open a new instance of Chess after a Save of app.lisp. Is there any way to live edit? I'll join the element discussion. Thanks! I am a Lisper, so this will become my new playground for fun and experimentation outside of the Windows/Mac/Linux world.

<No doubt I will have many demons in hell awaiting me...> Oh, you will sir! You and that rotten Rich Hickey fellow! ;)

So you wrote an assembler to replace NASM. Is it in the source? Why replace NASM? Thanks!
