    I'm really proud of this one. This is the amazing story of Ed Roberts and how he kickstarted the entire personal computer industry with the first successful personal computer, the Altair 8800. I got some great archive video footage of Ed and others who were there at the time being interviewed from 1996.

    Also, if you're wondering how you can get the REALLY COOL Micro-History t-shirt I'm wearing in the video, hey, just look up, and click the "Store" link on the top menu bar!

    Well, it took way longer than I anticipated, but it's finally here!



    This video tries to answer the age-old question: what was the FIRST personal computer? I go into a bit of a tangent in trying to define a computer first, and then go through the early history of digital computers, before finally getting around to answering the question. Maybe. You'll have to watch to find out!

    Here's a list of computers and their cool technical specs that I cover in this video, as a bonus for those of you reading this on the website:
