The Lisa is the first consumer grade GUI computer to come to market. The Xerox 8010 with the Star operating system preceded it by a couple years, but that was a high-end $50,000 (in 1981 dollars) workstation with big businesses as the target market. So it has some historical significance in that regard.
Ok, a Lisa 1 perhaps. Very few of those drives survived (for good reason, they were terrible) and most were upconverted to Lisa 2's.
I still have a Lisa Prodrive around here somewhere..... CZ
