Cool video about the Apple Lisa

In this video, Al Dblasi (ex-Apple guy) gives a complete rundown of the Lisa hardware and software. What is super interesting is that he worked for Apple when the Lisa came out and is intimately familiar with the history and technology of the device. For those who may not be familiar with it, the Lisa was the forerunner of the Mac.

For UI design, it gets super interesting about 9 minutes in.
