[comp.lang.forth] Chuck's 3-key keyboard

wmb@MITCH.ENG.SUN.COM (08/10/90)

The version I saw was a custom job, built from a business card and some
pieces of metal (I'm not kidding).  The keys were labeled RED , GREEN ,
BLUE and the 7 menu selections were displayed in red, green, blue,
cyan, magenta, yellow, and white.  You "composed" the color that you
wanted to select.

I don't remember exactly how he structured the menus to allow easy selection
of interesting "objects" (e.g. Forth words, letters, editor lines, whatever).
I just remember the basic idea, which is the use of colors as the basic
"alphabet".

One wonders how a color-blind person would fare with such a device?

Levels of gray perhaps?  Or maybe cross hatch patterns (360 degrees / 3
= lines at 120 degree angles).

I doubt that color is all that critical (what do you do on a B/W machine
anyway?)
