On the occasion of his passing, we pointed you in the direction of some of Steve Jobs's most revealing on-camera moments. Now, thanks to Public Broadcasting's WGBH, we have another one to add to the list.

The above video is a previously unreleased, 50-minute interview with Jobs done for the 1990 documentary on the rise of the computer, The Machine That Changed The World. In it, a 35-year-old Jobs (then trying to get NeXT computer off the ground) expounds on his famous line that computers are a "bicycle for the mind" and what made the original Macintosh stand a part.

"I think the Macintosh was created by a group of people who felt that there wasn't a strict division between science and art. Or in other words, that mathematics is really a liberal art if you look at it from a slightly different point of view. And why can't we interject typography into computers. Why can't we have computers talking to us in English language? And looking back, five years later, this seems like a trivial observation. But at the time it was cataclysmic in its consequences. And the battles that were fought to push this point of view out the door were very large."
