Hi Warner,
Just a few minor corrections.
1. slide 21: s/Murrey Hill/Murray Hill/
2. slide 18: s/IOCC/&C/
3. slide 28: s/strippe down/stripped down/; s/IOCC/&C/
Now I know why the domain name is ioccc.org and not iocc.org. Well-crafted
obfuscated C is nothing if not...unorthodox.
I hadn't even heard of VENIX before--great archeology! As you lusted for
that OS back in the '80s, I lusted after the Rainbow 100 itself, and found
it cool for the same reasons you did. The flexibility of the system was
appealing, keeping a bridge to my Z80 origins and the x86 juggernaut. As
it happened I wound up with a 6809 machine running OS/9, and got Unix-like
exposure without even knowing it (the text editor, T/S Edit, was a vi
clone, and the "word processor", T/S Word, a *roff clone). And best of
all, that machine taught me how to store multibyte integers correctly.
x86's worst-ever implementation of memory segmentation put me off of
assembly programming for years. When I finally saw sensible segmentation
combined with hardware memory protection, the universe made sense again.
You have a wealth of great material here and I think you will surprise some
people.
Regards,
Branden

OK. I've shared my slides for the talk.
Some of the family trees are simplified (V7 doesn't have room for all its
ports, for example)
Some of it is a little cheeseball since I'm also trying to be witty and
entertaining (we'll see how that goes).
Please don't share them around until after my talk on the September 20th
I'd like feedback on the bits I got wrong. Or left out. Or if you're in
this and don't want to be, etc.
All the slides after the Questions slide won't be presented and will
likely be deleted.

Please be kind (but if it sucks, please do tell). I've turned on
commenting on the slides. Probably best if you comment there.
I have a video of me giving this talk, but it's too rough to share...
Thanks for any help you can give me.
Warner
