[The Following is Taken From His Personal Site]

As mentioned, after a few years of working in other fields I finally ended up in software. My early years were spent exclusively working in Intel and Zilog assemblers. I wrote firmware (single board computers/devices), operating systems, and device drivers. I did lots of BIOS work.

I got interested in and worked in high resolution graphics for a long stretch. I still hold a couple of patents in that area.

I later returned to my early roots and worked once again in real-time and embedded systems working right at the hardware level. After starting off working "normal" jobs for a few years I then spent over 10 years working as a software consultant. This gave me the opportunity to perform a wide variety of jobs and work for a variety of companies.

Since that time I have returned to working "normal" jobs once again.
