Now, 40 years later, you can see exactly how the computer worked.<\/p>\n<p>Apple released the Lisa computer on January 19, 1983, as a high-end workstation computer with a mouse (a new concept at the time), a desktop interface, and bundled office productivity software. It ultimately wasn\u2019t a successful product, partially thanks to the sky-high price of\u00a0$9,995 (about $30,000 in 2022 dollars), but the Lisa laid the groundwork for the much more successful Macintosh computer that was released a year later.<\/p>\n<p>The Computer History Museum has partnered with Apple to release the source code for the Lisa\u2019s software, including its operating system and bundled applications. Much of the code is written in <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Pascal_(programming_language)\">Pascal<\/a>, an early programming language dating back to 1970, which was also used for some of the Mac\u2019s early software. There have already been a few interesting discoveries in the source code, including <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/lisalist2.com\/index.php\/topic,351.msg2535.html?PHPSESSID=mi1v166knn6dl0bq2cufi1kjto#msg2535\">references to a Lisa model called \u201cPepsi\u201d<\/a> (which might be the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.classic-computers.org.nz\/blog\/2011-03-05-rejuvenating-a-lisa2-10.htm\">Lisa 2\/10<\/a>), about <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/mastodon.social\/@jamesthomson\/109717984471801250\">eleven occurrences of the F-word<\/a>, and a few other <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/twitter.com\/madman_laughing\/status\/1616191359815192586\">entertaining comments<\/a>.<\/p>\n<lite-youtube videoid=\"wbO-vY9tbNY\" style=\"background-image: url('https:\/\/i.ytimg.com\/vi\/wbO-vY9tbNY\/hqdefault.jpg');\"><button type=\"button\" class=\"lty-playbtn\"><br \/>\n<span class=\"lyt-visually-hidden\">Play Video<\/span><br \/>\n<\/button>\n<\/lite-youtube>\n<p>Lisa\u2019s software was advanced for the time, and not just because it had a desktop environment in 1983. The Lisa operating system supported preemptive multitasking, so one application crashing wouldn\u2019t bring down the whole computer \u2014 a feature that didn\u2019t make it to Mac until the introduction of <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Mac_OS_X_10.0\">Mac OS X 10.0<\/a> in 2001. It also had protected memory and support for up to 2 MB RAM. Those features slowed down the computer\u2019s 5 MHz Motorola 68000 processor, causing the Lisa to feel slow even at its best.<\/p>\n<p>It\u2019s great to see the source code publicly available, since the Lisa was an important milestone in the history of computers. Maybe someone will try porting Lisa OS to modern hardware \u2014 the year of <span style=\"text-decoration: line-through;\">Linux<\/span> Lisa on the desktop could be upon us.<\/p>\n<p><small>Source: <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/computerhistory.org\/blog\/the-lisa-apples-most-influential-failure\/\">Computer History Museum<\/a><\/small><\/p>\n<\/div>\n<p><script async src=\"\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
