Allan Alcorn (born January 1, 1948) is an American pioneering engineer and computer scientist best known for creating Pong, one of the first video games.
Alcorn grew up in San Francisco, California, and attended the University of California, Berkeley, graduating with a Bachelor of Science degree in Electrical Engineering and Computer Sciences in 1971.
He worked for the pioneering video company Ampex, where he met Ted Dabney and several other people that would end up being constants through the Atari, Inc., Apple, Cyan Engineering and Pizza Time Theater (now known as Chuck E. Cheese’s) companies.
Alcorn was the designer of the video arcade game Pong, creating it under the direction of Nolan Bushnell and Dabney. Pong was a hit in the 1970s.
In addition to direct involvement with all the breakout Atari products, such as the Atari 2600, Alcorn was involved at some of the historic meetings of Steve Wozniak and Steve Jobs (at that time an Atari employee) presenting their Apple I prototype.
Alcorn was the person who hired Steve Jobs when he applied for a job at Atari in 1974. Jobs had seen a help-wanted ad in the San Jose Mercury newspaper for Atari that said “Have fun, make money.” He showed up in the lobby of the video game manufacturer wearing sandals and disheveled hair, and told the personnel director that he wouldn’t leave until he was given a job.

Adrian has been fixing vintage computers on his Youtube channel “Adrian’s Digital basement” since 2016. His first computer was a Commodore VIC-20 which he got in 1982 at the age of 7. This put him on a lifelong journey of tinkering and working with computers and technology which brings us today, where Adrian can often be found down in his basement making videos about troubleshooting and repairing broken vintage computers. Entirely self taught, Adrian specializes in pinpointing exactly what is wrong with a computer and explaining to his viewers how they can use logical thinking to figure out what has failed on the system. This allows for pinpoint repairs versus randomly replacing parts until the system works again.
Adrian is from Montreal Canada but now resides in Portland Oregon.
Rob Carnegie started his career in Canada near the end of the ‘70s, right in the middle of the mainframe era. As a programmer and later systems analyst he progressed through famous brands like Burroughs, IBM, Honeywell and Wang VS. Rob‘s interest in micro computing goes back that far as well. He was one of the early adopters, purchasing an Apple II in 1979 and an IBM 5155 in 1985. Rob still owns every computer he ever purchased, as well as every magazine, brochure and SWAG item that ever came his way. His collection includes systems as small as the COSMAC Elf to as large as an IBM AS/400. Rob is a founder of the Chilliwack Retro Computing club, which draws members from throughout the greater Vancouver BC area. The club meets monthly in Cowork Chilliwack and attends several special events annually.

Tramiel received his bachelor of science degree in physics from Santa Clara University in 1976 and earned his master of arts, master of philosophy, and doctorate of philosophy degrees—all in physics—from Columbia University. He worked in the Columbia Astrophysics Lab under advisor Professor Gary Chanan, now at the University of California at Irvine.
Fresh out of graduate school, Tramiel joined his father and two brothers when his father bought Atari from Warner Communications in 1984. For the next 12 years, Tramiel was involved in the development of Atari’s products as vice president of software, managing an internal group of a dozen programmers while interacting worldwide with software developers and contract programmers.
Since retiring from Atari at age 42, he has been concentrating on advocating science education (See Forbes magazine, Oct. 30, 2000, for his work to improve the quality of science textbooks with the California Department of Education). Tramiel has also been a volunteer eighth-grade astronomy teacher for the past 10 years and has been volunteering at the Chabot Space and Science Center since 2000.
“I think that CFI’s mission of fostering a society based on reason and values is wonderful, in fact vital, for the future of humanity,” Tramiel said.
Hello. I work in a rented lab space under Dr Evil’s volcano, where I build robots and restore pieces of vintage tech assisted by my faithful minions.
Well, I wish. In real life, I am a tech executive in Silicon Valley. I hold a Ph.D. in Opto-Electronics from University of Paris. I am a former Bell Labs researcher, an Intel Fellow and founder of several tech startups in Silicon Valley, all related to high-speed fiber optics communications. I have over 60 U.S. patents and published over 100 refereed research papers.
In 2009, I started building an R2-D2 robot just for fun. Then, in 2015, I became a volunteer at the Computer History Museum in Mountain View, CA, working on the IBM 1401 Restoration Team. At the Museum, I met many like-minded tech historians and restorers (in particular Carl Claunch and Ken Shirriff who appear frequently in my videos), and it all went downhill from there.
My well-equipped basement lab, which was originally dedicated to serious startup development work, is now put to fun use for R2-D2 building, test equipment, and vintage computers restorations. Which is an outlet for my engineering passion, since they don’t let me turn the knobs in the lab at work anymore. Under the pseudonym CuriousMarc, I make videos of these enginerding adventures on YouTube.
As you’ll quickly realize, I concentrate on highly engineered, tour-de-force pieces that represent the best of their time and could not be easily replicated today. The more clever and contrived the better. In my choice of pieces, I also pay attention to the intrinsic beauty of the engineering and design. I want to celebrate engineering so good, it has almost turned into art.
Working on this old stuff forces me to deal with the very fundamentals of electronics (and electro-mechanics). The principles are exactly the same as today, but nothing is hidden in mysterious circuits – you can understand and fix everything. Years of Moore’s law has sure given us gobs of transistors, oceans of memory and a glut of gigacycles, but many times, particularly in consumer hardware, these are simply used to cover up poor and inefficient designs – and resource devouring software. What Intel giveth, Microsoft taketh away, as they say. It often irritates me that my PC takes many seconds to react to a simple command, in which time it has executed many billions of unnecessary instructions and consumed a few gigabytes of memory, no one knowing exactly what for anymore. Nothing like this in old hardware: designs are pure and efficient, and the lack of resources is compensated by engineering mastery and immense cleverness, which is a joy to reverse engineer. Not only does it teach us timeless electrical fundamentals and engineering tricks, but it also gives us a much better appreciation of today’s tech. How did all the technology we take for granted came to be? It will make you a far better engineer and inventor if you take the time to be a thorough student of the inventions of your illustrious predecessors.
Finally, and this is the cherry on the cake, I sometimes have the privilege to meet the very inventors, engineers and entrepreneurs that built these exceptional machines. And then I can actually engage in knowledgeable engineering conversations with them! I have met the inventors of the laser diode, the Xerox Alto, the IBM 1401, the Ethernet, and many of the people that built and programmed the Apollo guidance computer. And that, my friends, is priceless.
