@th @cypnk things have moved on a bit since that screenshot... there's a bootable colorForth (dd it onto the tiniest of USB drives and it comes up more or less instantly! much quicker than the BIOS... legacy mode only though) at http://www.inventio.co.uk/LegacyIndex.htm - and one that runs under windows (i guess, for practicality? it doesn't interact with windows at all, it just runs under it) is still available from http://www.greenarraychips.com/home/support/download-02b.html
they've diverged somewhat; the GreenArrays one is the one Chuck built (which GA have now thrown overboard) whereas Howerd Oakford seems to have strived to have something practical yet native
@cypnk Or `colorForth`? Which is like normal FORTH, except that the colors are significant:
> Comments are in BLUE, : is not used, instead a RED word is the name of a new defintion. GREEN words are being compiled and WHITE words are being executed. Later [Chuck] plans to make numbers a different color.
