VCF East: Xerox Star vs. Apple Lisa

Meh. the Lisa was absolutely, positively, explicitly NOT a Mac. If you don't get that, then you misunderstand the business of computing in the late 70s / early 80s. The author also ignored Jef Raskin's work on the original Mac project (I wrote a serial driver for him in the early 80s for a 6809 prototype he was working on.) If you're going to make one of these Mac hagiographies, it's useful to point out the Canon Cat (which was more in line with Jef's original idea for the Mac) and then point out how different it was from main-stream Macs. And then point out WHY the Lisa was not a Mac. So... Why do people think the Lisa was a prototype Mac? It's easy to understand the confusion. It has a 68k processor, a mouse and a bitmap screen. It was even used as a development platform for the original Macs. But it is not a Mac. The Lisa didn't have "apps" and "files" in the same way we think about them. It had "tools" and "documents." The Lisa was strongly influenced by the Xerox Star. And while it's not exactly true to say the Lisa was Apple's version of the Star, there was definitely a strong resemblance. The Lisa (and the Star) came with all the functionality it would ever have built into the system. (This restriction changed later, but when launched, it was considered a complete system.) It had "apps" in the sense there were tool icons you could (double?) click to create a blank document of a specific type. But it took Apple over a year to decide they wanted to give third-parties the

I remember trying out Plan 9 a few years ago. I like its underpinnings; I like how the designers pushed the Unix notion of "everything is a file" to its limits, with various services being presented to the operating system as file servers implemented using a protocol named 9P. It's a cool research operating system with a lot of very interesting ideas, but ultimately it's not my daily driver due to a lack of hardware and software support, though I am working on a research project (but for conventional *nix operating systems) that takes advantage of 9P. Carmack's description of the rio GUI is apt; rio is heavily based on Xerox PARC's Cedar environment from the mid-1980s ( link ). I had a hard time getting used to rio, though eventually I learned it. I even purchased an old Sun three-button mouse (with no click-wheel) since Plan 9 didn't like my click-wheel mouse. rio does not adopt a lot of the conventions that were introduced by the Apple Lisa, Apple Macintosh, and Microsoft Windows, resulting in a completely foreign experience for most new Plan 9 users. There is a misconception that Apple and Microsoft simply stole the idea of GUIs from Xerox PARC without further innovating on it. This misconception is false; the Apple Lisa and the Apple Macintosh introduced many GUI conventions that were not present in Xerox PARC's GUIs (this video comparing the Apple Lisa to the Xerox Star highlights the differences: ▶ this video ), and Windows introduced additional innovations.
