You may remember a couple of years ago I posted about an Apple Lisa demonstration video from 1984. (If not, you can find it here).
Well, the guy that did it — Alfred — posted a video back in August that is an almost 22 minute in-depth look at the Apple Lisa. Every inch of the machine is covered. He starts by taking it apart, then eventually gets to the UI and all of that.
If you’re into this kind of thing, this is a fascinating look at the system.
