If you remember the posts about experimental one pin oscillator some time 
ago, here's an excerpt from Chuck Moore's blog 
(http://colorforth.com/blog.htm):

Jeff Fox has died of a heart attack. He was a wonderful character and a 
long-time Forth enthusiast. His website ultratechnology.com is a fount of 
information about Forth and Forth chips. Jeff was a good friend and 
supported my chips with money and effort. I'll miss him.

There is a thread in the comp.lang.forth group about using the GA144
in "killer apps".  I would like to hear any comments folks might
have.
