{"guid":"c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","title":"Ignored, Disposed of, Revived","subtitle":"Four Decades of Apple's Lisa","slug":"vcfb2023_-_193_-_en_-_202310151500_-_ignored,_disposed_of,_revived_-_michael_engel","link":"https://c3voc.de","description":"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 – 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 – 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.","original_language":"eng","persons":["Michael Engel"],"view_count":227,"promoted":false,"date":"2023-10-15T15:00:00.000+02:00","release_date":"2023-10-17T00:00:00.000+02:00","updated_at":"2026-05-02T05:30:02.667+02:00","tags":["vcfb2023","193","2023",""],"length":5130,"duration":5130,"thumb_url":"https://static.media.ccc.de/media/events/vcfb/2023/193-c7b3a34c-c3c4-a276-89f6-ed42600c0e3e.jpg","poster_url":"https://static.media.ccc.de/media/events/vcfb/2023/193-c7b3a34c-c3c4-a276-89f6-ed42600c0e3e_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/vcfb/2023/193-c7b3a34c-c3c4-a276-89f6-ed42600c0e3e.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/vcfb/2023/193-c7b3a34c-c3c4-a276-89f6-ed42600c0e3e.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/vcfb2023_-_193_-_en_-_202310151500_-_ignored,_disposed_of,_revived_-_michael_engel","url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_title":"Vintage Computing Festival Berlin 2023","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23","related":[],"recordings":[{"length":5130,"mime_type":"video/mp4","language":"eng","filename":"vcfb23-193-eng-Ignored_Disposed_of_Revived_hd.mp4","state":"new","folder":"h264-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2023-10-17T17:01:54.112+02:00","label":"eng 1080p","size":805,"recording_url":"https://cdn.media.ccc.de/events/vcfb/2023/h264-hd/vcfb23-193-eng-Ignored_Disposed_of_Revived_hd.mp4","url":"https://api.media.ccc.de/public/recordings/71153","event_url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23"},{"length":5130,"mime_type":"audio/mpeg","language":"eng","filename":"vcfb23-193-eng-Ignored_Disposed_of_Revived_mp3.mp3","state":"new","folder":"mp3","high_quality":false,"width":0,"height":0,"updated_at":"2023-10-17T17:24:34.191+02:00","label":"eng","size":78,"recording_url":"https://cdn.media.ccc.de/events/vcfb/2023/mp3/vcfb23-193-eng-Ignored_Disposed_of_Revived_mp3.mp3","url":"https://api.media.ccc.de/public/recordings/71159","event_url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23"},{"length":5130,"mime_type":"audio/opus","language":"eng","filename":"vcfb23-193-eng-Ignored_Disposed_of_Revived_opus.opus","state":"new","folder":"opus","high_quality":false,"width":0,"height":0,"updated_at":"2023-10-17T17:26:33.879+02:00","label":"eng","size":58,"recording_url":"https://cdn.media.ccc.de/events/vcfb/2023/opus/vcfb23-193-eng-Ignored_Disposed_of_Revived_opus.opus","url":"https://api.media.ccc.de/public/recordings/71160","event_url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23"},{"length":5130,"mime_type":"video/mp4","language":"eng","filename":"vcfb23-193-eng-Ignored_Disposed_of_Revived_sd.mp4","state":"new","folder":"h264-sd","high_quality":false,"width":720,"height":576,"updated_at":"2023-10-17T22:23:49.771+02:00","label":"eng 576p","size":206,"recording_url":"https://cdn.media.ccc.de/events/vcfb/2023/h264-sd/vcfb23-193-eng-Ignored_Disposed_of_Revived_sd.mp4","url":"https://api.media.ccc.de/public/recordings/71174","event_url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23"},{"length":5130,"mime_type":"video/webm","language":"eng","filename":"vcfb23-193-eng-Ignored_Disposed_of_Revived_webm-sd.webm","state":"new","folder":"webm-sd","high_quality":false,"width":720,"height":576,"updated_at":"2023-10-21T02:08:29.709+02:00","label":"eng 576p","size":308,"recording_url":"https://cdn.media.ccc.de/events/vcfb/2023/webm-sd/vcfb23-193-eng-Ignored_Disposed_of_Revived_webm-sd.webm","url":"https://api.media.ccc.de/public/recordings/71290","event_url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23"},{"length":5130,"mime_type":"video/webm","language":"eng","filename":"vcfb23-193-eng-Ignored_Disposed_of_Revived_webm-hd.webm","state":"new","folder":"webm-hd","high_quality":true,"width":1920,"height":1080,"updated_at":"2023-10-21T06:48:10.304+02:00","label":"eng 1080p","size":875,"recording_url":"https://cdn.media.ccc.de/events/vcfb/2023/webm-hd/vcfb23-193-eng-Ignored_Disposed_of_Revived_webm-hd.webm","url":"https://api.media.ccc.de/public/recordings/71295","event_url":"https://api.media.ccc.de/public/events/c7b3a34c-c3c4-a276-89f6-ed42600c0e3e","conference_url":"https://api.media.ccc.de/public/conferences/vcfb23"}]}
