|The party featured several of the folks who created the Alto. I sure wasn't one of them, but I was involved in the history of the Xerox Star.
In the early 1990s, after Apple had already made a success of the Mac, Xerox was still trying to make a success of the Star product line. My first job out of college was working on Viewpoint and GlobalView, the last two incarnations of the Star operating system. I may have been the last guy to add new features to the "Star desktop" code. There were a great bunch of people at Xerox and I learned a lot about quality engineering.
Viewpoint ran on the Xerox 6085, which kicked butt on IBM PCs with nominally similar hardware specs. This 6085 is running XDE, the Xerox Development Environment, rather than Viewpoint. Many engineers who used XDE remember it with more fondness than Viewpoint itself.
