Run py65mon -m 65c02 -r cthulhu-py65mon.bin from this directory.
Cthulhu Scheme is a very, very primitive version of a bare-metal Scheme-like
language for the 65c02 8-bit MPU. The aim is to see how far you can go with the
limited hardware available. It is free -- released in the public domain -- but
with absolutely no warranty of any kind. Use at your own risk! (See
COPYING.txt for details.)
At the moment this is pre-alpha software, which means that it will assemble and
probably even run on a good day, but won't do anything useful yet. Actually,
pretty much the only thing it will do at this point is echo bools, strings, some
number types, oh and you can actually quit with (exit). Part of this is
because I am using this project to get familiar with the 64tass assembler (see
http://tass64.sourceforge.net/#conditional-assembly) so there are a lot of
moving parts at the moment.
Honestly, you might want to come back in a few months.
Note that the testing suite is also still very primitive - all it does is run a bunch of commands, and if it doesn't crash, all is well. This will be updated once we get more commands going.
See docs\manual.html for the Cthulhu Scheme manual, which at some point will
cover the installation, setup, tutorials, and internal structure. Once this
project actually has something to write home about, I'll be announcing it
formally on 6502.org.
