I assume not with his version that talks directly to the 
hardware.  Since there are implementations of CF that
run on windows machines then maybe take a look
here

VNC runs on lots of OS including :
Windows 9x/2000/NT/XP (x86)
Linux (x86)
Solaris 2.5 (SPARC)

I mis-stated this.  Actually it was a test of a screen full of 
generic Forth on a windows notebook, not actually 
Chuck's computer screen.

I wonder if it will be impossible to show his screen, since
he works so closely to the hardware. :-(

My guess is that it is close to what we used to call a 
TSR.

I have not yet tried out ColorForth here. Let me know 
what you find out if you try it. I am available to help with
VNC even though it is quite a friendly system, it is always
easier with some help.  My plate is full with
converting my estimating application from DOS
to windows, improving WinEd and testing and playing
with 4ePost, as well as my Electrical contracting business.
