ChipForth documentation

Is there any online documentation for ChipForth?  I don't see any
mention of it in the Polyforth manual that was on the Green Arrays web
site a while back.  I don't know if it was a regular part of Polyforth.

Meanwhile, if anyone is interested, I just noticed that greenarrays.com
itself now reports:

    Latest developments: As of 1 May 2024, we have completed the process
    of moving our headquarters offices and lab from Cheyenne, Wyoming,
    to rural Northern Missouri. This is a particularly healthy part of
    the United States, in which we may operate more sustainably than is
    possible in a city such as even Cheyenne whose increasing
    urbanization and expansion seem to proceed without regard for the
    quality of life conducive to balanced, creative thinking. One
    exciting aspect of our new location is that we anticipate meeting
    many youngsters who would like to learn how to design and program
    chips such as ours without having to leave the pleasant environments
    in which they were raised. Relatively minor hiccups are likely as
    our facilities and processes adjust, but the website is up again and
    we are ready to resume taking orders and delivering products. None
    of our contact information has changed other than the physical
    address of headquarters.
