The Lisa was Apple's first computer featuring a graphical user interface (GUI). Whereas previous systems developed at Xerox PARC never had a significant commercial impact, Lisa was intended to change this. Unfortunately, this turned out to be a failure \u2013 not least due to internal competition by the Macintosh at a quarter of the price, but also due to internal politics at Apple. Ultimately, the Lisa was relegated to be a high-end Mac and, in 1989, Apple buried about 2700 Lisas in a landfill in Utah to get a tax write-off. Still, the Lisa is not forgotten. In early 2023, forty years after its introduction, Apple and the CHM have published source code to the Lisa software, including system and application software \u2013 and there are alternative systems available such as Xenix, GEMDOS, and Smalltalk. Today, not only emulators for the Lisa exist, but work is also in progress to build a clone of the Lisa PCBs in order to repair existing machines or create new ones. This talk gives an overview of the history of Lisa's hard- and software and discusses challenges in maintaining, emulating and recreating the system.\nabout this event: https://c3voc.de
