Technically, the first eletrical computer I owned was a Nintendo Entertainment System (NES)... quite a few years ago, while I was still in elementary school. Correspondingly, it might be fitting that the history of the Famicom/NES is not completely serious.

It started with a phone call in 1981. President Yamauchi told me to make a video game system, one that could play games on cartridges. He always liked to call me after he’d had a few drinks, so I didn’t think much of it. I just said, “Sure thing, boss,” and hung up. It wasn’t until the next morning when he came up to me, sober, and said, “That thing we talked about—you’re on it?” that it hit me: He was serious.
