The repository also contains the compressed image of mimosa for running Gambit on bare metal. You can copy the image to a real IDE HDD and use it to boot a real PC, or use the QEMU emulator like this:
% gunzip -c mimosa.img.gz > mimosa.img % qemu-system-i386 -m 1G -hda mimosa.img
Once booted, here are some interesting things to type at the Gambit REPL:
> (current-directory) > (directory-files) > (load "fact.scm") > (load "fib.scm") ;; run it interpreted > (compile-and-load "fib.scm") ;; run it compiled to x86 > (load "x86-asm.scm") ;; x86 assembler example > (load "x86-os.scm") ;; read RTC with in/out instructions > (edit "fib.scm") ;; save/exit with ESC key
Very promising! I was able to run all of these examples with QEmu.
It's very nice that there's a built-in editor.
Also tried with VirtualBox. It needs the disk image in qcow2 format: `qemu-img convert -f raw -O qcow2 mimosa.img mimosa.qcow2`. Runs fine up to "The len of the gambit file is: 9569 520" but then hangs at full CPU usage. Let me know if there's some way I can try to get useful debug info.
