One of my favourites. Henry is an interesting guy but it has been years
since I've talked with him in person. He's also responsible for 
"The Amazingly Workable Formatter".

*chuckle* A pointer isn't just an int anymore now. ;) 

Amusingly years ago I worked for Computing Devices Canada that used some
CDC computers. I was told through a very reliable source that they 
got Unix ported to the Cyber by SoftQuad based in Toronto. They were
well known as a 'troff house' at this time. I'm told they wrote a PDP-11
emulator for the Cyber and that's how they got Unix on the Cyber. ;)
