Please retell the story of how you got started in Model Rocketry and some of your earlier projects, successes, and of course failures. Be sure to name names and clubs!

It all began way back in 1967 in Colorado Springs when my dad took me to a model rocket meeting staged by what became Estes Industries. For Christmas that year I received an Aerobee-Hi rocket kit. The rocket was quickly built and reached an altitude of 671 feet on its first flight. Before we moved to Colorado, where my dad was assigned as project officer for the Air Force Academy Chapel, I was seated in a hot seventh-grade classroom at Hamilton Junior High School watching a big fan by the door when the idea of a ram-air controlled rocket popped into my mind. The idea was a rocket that was steered not by fins but by air entering the open nose of a rocket and then jetted out ports in the nose cone. This project dominated my experimenting for several years, and its successes and failures will be covered in detail in the new memoir. The major success was confirmation that the ram air principle actually worked during test flights. The biggest failure was that the best made sun-homing test rocket control section worked great—but failed miserably during ground tests (suspended from a string looking at a flashlight) when the ram air scanner rapidly stopped during a course change and its inertia caused the entire rocket to spin.

The ram air project involved many test flights, and night flights were best since the rocket path could be easily recorded on film. To recover these rockets, I built a very small 2-transistor light flasher (which I still have). When I demonstrated the flasher during a night launch at a model rocket meeting in Portales, New Mexico, in 1969, George Flynn, editor of Model Rocketry magazine, asked me to write an article about its construction. I build a new flasher for the article, which was published in September 1969. I was very surprised when Flynn sent a check for $93.50 for the article. I told my wife Minnie that I wanted to become a freelance writer and showed my friend Ed Roberts the article. Ed and I were both assigned to the Air Force Weapons Laboratory in Albuquerque, NM, at the time, and we often discussed forming a company to sell electronic kits through Popular Electronics and Radio-Electronics magazines. When Ed saw the article in Model Rocketry, he agreed it was time to start a company. We invited Stan Cagle and Bob Zaller to join us in a meeting at Ed’s house, where we decided to call the company Micro Instrumentation and Telemetry Systems (MITS). You can read the details on my web site. Our first product was my light flasher circuit. I left both MITS and the Air Force after a year or so to become a freelance writer but stayed connected by writing manuals for various MITS products. I also arranged a meeting with Ed and Les Solomon of Popular Electronics when Les came to visit my wife Minnie and me. That meeting led to the Opticom article (a MITS light-wave communication system), various calculator articles and finally a cover story in January 1975 on the MITS Altair 8800, a microcomputer designed by Ed. The Altair was featured on the cover, which attracted Paul Allen’s attention. He bought the magazine in a Harvard Square news store and immediately took it to his high school friend Bill Gates. Within months, Paul was working at MITS, and Bill followed later. They organized Microsoft shortly thereafter. Paul Allen planned a great exhibit on the early days of microcomputing, which began in Albuquerque, not the West Coast. The exhibit is called STARTUP. It occupies an entire gallery at the New Mexico Museum of Natural History and Science in Albuquerque. On display are the first BASIC tape, early computer stuff, and the light flasher (and rocket) I built for Model Rocketry magazine.
