Up until 2001 I worked for Silicon Graphics doing this sort of stuff:
- Software developers may enjoy visiting my Developer's Corner
-
I ported AutoCAD R12 and R13 to SGI's Irix operating system: AutoCAD
- I also put together a collection of software formerly known as the SGI-AutoCAD Bonus Pack located here.
-
I have a passing knowledge of 3D
Studio and the 3DS
network renderer for IRIX.
-
I used to work on the IrisVision
3D graphics accelerator for Microchannel and AT bus PCs.
- My latest and greatest PC information is available here as well.

Eventually, that web site was converted to a dedicated web hosting server at that same company (AmHosting, now JetHost) and is now servered via HTTPS/SSL:
