If you haven't seen me in a while, you may be shocked to see I have gone to pot.The world of patents is an interesting, frustrating, fickle place. I have a few patents with my name on them.
Web sites that I maintain in varying levels of committment
The most mysterious thing about me is my email address, frustum@pacbell.net. It wasn't my first choice of names, but just about everything was taken. At the time I picked it, I was designing chips for drawing 3D images. For reasons we won't get into here, there is a geometric shape of some significance known as a frustum. What is a frustum? I'm glad you asked. If you take a pyramid (a tetrahedron) and clip off the top, the top bit is still a tetrahedron. The bottom part is called a frustum. No, not frustrum, but frustum. Look on the back of a U.S. $1 bill, and there one is, right beneath the mysterious eye.

I went through a long phase of collecting more things than I have time for. Now I'm down to a handful of machines that I can concentrate on. If you have any of the following to copy, donate, or sell, please contact me. Lust List
- Wang 2200 software; OS releases, games, things of general interest
- Wang newsletters, especially the 70s and 80s that cover the lifespan of the 2200 family
- Compucolor II software and documents
- Information (esp. instruction set and architecture) on the BTI Computer Systems BTI-8000. My first job out of college was at BTI; the week after I arrived they started round after round of layoffs. I was there a year, and now twenty years later, I'm curious about what it was that I was working on! Hopefully this list of a few names might trigger some ex-BTI'er to find this page via a search engine: Jeff Libby, John Kinsel, Hal Sparks, Eric Schmidt, Bob Ruiz, Ron Crandall, Bill Quackenbush. If you recognize one of these people, email me please!
