   You probably mean "direct threaded" or "indirect threaded". Subroutine threading is when the VM code compiles to subroutine call instructions that the host computer can execute directly.

   How's this for simple? It's a stack machine with 11 instructions. https://github.com/larsbrinkhoff/nybbleForth/blob/c/nybble.c The original interpreter was written in Forth, but I'll spar

   Cue smug lispers.

   Maybe look into colorForth, where the colors are not just syntax highlighting, but part of the language semantics.

   It seems more likely that PRIMOS would have been influenced by Multics.

   I was looking for Ron Schnell's original Maclisp verison of the DUNNET game. He said it might be on backup tapes from MIT-EECS. But I suspect such backups do not exist any more.

   It's been 30 years, and the people are still obsessing about gerbils and Jerry Pournelle?!?

   OZ was always TOPS-20. Or Twenex, as they called it. Actually the new KS10 AI may have been running TOPS-20 briefly before the ITS port was done.

    You should consult the Maclisp manuals. There is one in ITS, and the Pitmanual is here: http://maclisp.info/pitmanual/index.html You should probably also test some code in Maclisp.

    > I wanted a language that would be (a) faster to program in (than assembly) but be (b) fast when running. It needed to be pretty efficient. Forth. Problem solved.

    If you want to expand your brain even more, try making a self-hosting Forth compiler.

    There's also an effort to decap the ASICs and take die photos to reverse engineer the schematics: http://www.atari-forum.com/viewtopic.php?t=29658 (Shifter, display controller) http://www.atari-forum.com&#x2

    I don't see that Gforth can create executables. It can create image files, but those are not directly executable; they need to be loaded by the Gforth runtime.

    My personal Forth can write Linux ELF and Windows PE executables. (I don't have access to a Mac, so OS X Mach-O is out.) http://github.com/larsbrinkhoff/lbForth

    I believe one major motivation behind Carp is the lack garbage collection. Or rather, avoiding GC pauses. So, maybe you could benchmark Carp vs SBCL in that area?

    The compiler does lifetime analysis, and there is a "reference borrowing" concept like in Rust.

    Maybe you can use "Readable Lisp S-expressions". http://readable.sourceforge.net/

    There's (or was) Game Oriented Assembly Lisp: https://en.wikipedia.org/wiki/Game_Oriented_Assembly_Lisp

    As far as I understand from listening to Erik talk about Carp, there is an interactive interpreter which does use GC. In contrast, the compiler generates GC-free code.
