When I left Oxford, I didn’t have any role models for doing a second degree. I didn’t know anybody who’d done one. I didn’t know how to go about doing it. What I probably should have done is go to Berkeley and do a master’s or Ph.D. in computer science, but I didn’t know about that. So I went and joined a telecommunications company down on the south coast of England, and I used the fact that I knew about microprocessors, and I was one of the few people that did. So I was in demand, and I was in demand as a consultant.
