112-624: Lisa is a desktop computer developed by Apple , produced from January 19, 1983 to August 1, 1986, and succeeded by Macintosh . It is generally considered the first mass-market personal computer operable through a graphical user interface (GUI). In 1983, a machine like the Lisa was still so expensive that it was primarily marketed to individual and small and medium-sized businesses as a groundbreaking new alternative to much bigger and more expensive mainframes or minicomputers such as from IBM , that either require additional, expensive consultancy from
224-401: A UPS to handle electrical disturbances like short interruptions, blackouts, and spikes; achieving an on-battery time of more than 20–30 minutes for a desktop PC requires a large and expensive UPS. A laptop with a sufficiently charged battery can continue to be used for hours in case of a power outage and is not affected by short power interruptions and blackouts. A desktop computer often has
336-405: A graphical user interface (GUI) to be sold commercially. It uses a Motorola 68000 CPU clocked at 5 MHz and has 1 MB of RAM. It can be upgraded to 2 MB and later shipped with as little as 512 kilobytes. The CPU speed and model were not changed from the release of the Lisa 1 to the repackaging of the hardware as Macintosh XL. The real-time clock uses a 4-bit integer and the base year

The case may be oriented horizontally or vertically and placed either underneath, beside, or on top of
560-834: A tower is a form factor of desktop computer case whose height is much greater than its width, thus having the appearance of an upstanding tower block . In computing , a pizza box enclosure is a design for desktop computers. Pizza box cases tend to be wide and flat, resembling pizza delivery boxes and thus the name. Cube Workstations have a cube case enclosure to house the motherboard , PCI-E expansion cards, GPU , CPU , DRAM DIMM slots, computer cooling equipment, chipsets , I / O ports, hard disk drives , and solid-state drives . Gaming computers are desktop computers with high performance CPU , GPU , and RAM optimized for playing video games at high resolution and frame rates . Gaming computer peripheries usually include mechanical keyboards for faster response time, and
672-619: A 12-inch (30 cm) screen. Lisa's printer support includes Apple's Dot Matrix , Daisy Wheel , and ImageWriter dot matrix printers, and Canon 's new color inkjet technology. The original Lisa, later called the Lisa 1, has two FileWare 5.25-inch double-sided variable-speed floppy disk drives, more commonly known by Apple's codename "Twiggy". They have what was then a very high capacity of approximately 871 kB each, but are unreliable and use proprietary diskettes. Competing systems with high diskette data storage have much larger 8" floppy disks, seen as cumbersome and old-fashioned for
784-460: A Lisa from the estate of Microsoft co-founder Paul Allen was sold for $ 882,000. Desktop computer A desktop computer , often abbreviated as desktop , is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer ) due to its size and power requirements. The most common configuration has a case that houses the power supply , motherboard (a printed circuit board with
896-618: A Mac, with the exception of the even more inexpensive Mac Mini (albeit without a monitor and keyboard), and the MacBooks are the top-selling form factors of the Macintosh platform today. The decades of development mean that most people already own desktop computers that meet their needs and have no need of buying a new one merely to keep pace with advancing technology. Notably, the successive release of new versions of Windows (Windows 95, 98, XP, Vista, 7, 8, 10 and so on) had been drivers for
1008-645: A PhD, the university was not accredited for a PhD in computer science. The first original computer application he wrote was a music application as part of his master's thesis. Raskin later enrolled in a graduate music program at the University of California, San Diego (UCSD), but quit to teach art, photography, and computer science there. He worked as an assistant professor in the Visual Arts department from 1968 until 1974. There, he presented shows about toys as works of art. Raskin announced his resignation from
1120-428: A Professor at MIT . Raskin discouraged using the informal term " intuitive " in user interface design, claiming that easy to use interfaces are often due to exposure to previous, similar systems, thus the term "familiar" should be preferred. Aiming for "intuitive" interfaces (based on reusing existing skills with interaction systems) could lead designers to discard a better design solution only because it would require
1232-484: A ZUI or Zooming User Interface . In the same period, Raskin accepted an appointment as Adjunct Professor of Computer Science at the University of Chicago 's Computer Science Department and, with Leo Irakliotis , started designing a new curriculum on humane interfaces and computer enterprises. His work is being extended and carried on by his son Aza Raskin at Humanized, a company that was started shortly after Raskin's death to continue his legacy. Humanized released Enso,

Laptops also commonly integrate wireless technologies like Wi-Fi , Bluetooth , and 3G , giving them a broader range of options for connecting to the internet, though this trend is changing as newer desktop computers come integrated with one or more of these technologies. A desktop computer needs
1456-637: A commercial success. Raskin claimed that its failure was due in some part to Steve Jobs, who successfully pitched Canon on the NeXT Computer at about the same time. It has also been suggested that Canon canceled the Cat due to internal rivalries within its divisions. After running a cryptic full page advertisement in the Wall Street Journal that the "Canon Cat is coming" months before it was available, Canon failed to follow through, never airing
1568-465: A consumer system. Lisa 1's innovations include block sparing, to reserve blocks in case of bad blocks, even on floppy disks. Critical operating system information has redundant storage, for recovery in case of corruption. The first hardware revision, the Lisa 2, was released in January 1984 and was priced between $ 3,495 and $ 5,495 . It was much less expensive than the original model, and dropped
1680-697: A decision reached simultaneously by others at Apple who had stronger authority on the issue. Raskin later stated that were he to redesign the mouse, it would have three clearly labeled buttons—two buttons on top marked "Select" and "Activate", and a "Grab" button on the side that could be used by squeezing the mouse. It has the three described buttons (two invisible), but they are assigned to different functions than Raskin specified for his own interface and can be customized. In 2005, Macintosh project member Andy Hertzfeld remembered Raskin's reputation for often inaccurately claiming to have invented various technologies. Raskin's resume from 2002 lends credence by stating he
1792-549: A decline in sales, in 2018, global PC sales experienced a resurgence, driven by the business market. Desktops remain a solid fixture in the commercial and educational sectors. According to the International Data Corporation (IDC) , PC sales shot up 14.8% between 2020 and 2021 and desktop market grew faster than the laptop market in the second quarter of 2021. Total PC shipments during 2021 reached 348.8 million units, up 14.8% from 2020. This represents
1904-420: A desk. Desktop computers with their cases oriented vertically are referred to as towers . As the majority of cases offered since the mid-1990s are in this form factor, the term desktop has been retronymically used to refer to modern cases offered in the traditional horizontal orientation. Prior to the widespread use of microprocessors , a computer that could fit on a desk was considered remarkably small;

The hardware is more advanced overall than the following Macintosh, including hard disk drive support, up to 2 megabytes (MB) of random-access memory (RAM), expansion slots, and a larger, higher-resolution display. Lisa's CPU and the storage system were strained by the complexity of the operating system and applications, especially its office suite , and by

It was affected by its high price, insufficient software, unreliable FileWare ( codename Twiggy) floppy disks , and the imminent release of the cheaper and faster Macintosh . Only 60,000 Lisa units were sold in two years. Lisa was considered a commercial failure but with technical acclaim, introducing several advanced features that reappeared on the Macintosh and eventually IBM PC compatibles . These include an operating system with memory protection and
2352-431: A gaming computer mouse which can track higher dots per inch movement. These desktops are connected to home entertainment systems and typically used for amusement purpose. They come with high definition display, video graphics, surround sound and TV tuner systems to complement typical PC features. Over time some traditional desktop computers have been replaced with thin clients utilizing off-site computing solutions like

#17327656498482464-618: A growth of 33% compared to 2006. In 2008, it was estimated that 145.9 million notebooks were sold and that the number would grow in 2009 to 177.7 million. The third quarter of 2008 was the first time when worldwide notebook PC shipments exceeded desktops, with 38.6 million units versus 38.5 million units. The sales breakdown of the Apple Macintosh has seen sales of desktop Macs staying mostly constant while being surpassed by that of Mac notebooks whose sales rate has grown considerably; seven out of ten Macs sold were laptops in 2009,
2576-428: A linguistic command-line interface, which is based on Jef's work and dedicated in his memory. In early 2008, Humanized became part of Mozilla . The Archy project never included a functional ZUI, but a third party developed a commercial application called Raskin inspired by the same Zoomworld ZUI idea. Raskin expanded the meaning of the term "cognetics" in his book The Humane Interface to mean "the ergonomics of

Privately, Hertzfeld and the other software developers used "Lisa: Invented Stupid Acronym", a recursive backronym , and computer industry pundits coined the term "Let's Invent Some Acronym" to fit Lisa's name. Decades later, Jobs told his biographer Walter Isaacson : "Obviously it

His artwork was displayed at New York's Museum of Modern Art as part of its permanent collection, the Los Angeles County Museum of Art, and the University of California, San Diego. He received a patent for airplane wing construction, and designed and marketed radio controlled model gliders . He

Internal, hosted virtual desktops can offer users a completely consistent experience from anywhere. Workstations are advanced class of personal computers designed for a user and more powerful than a regular PC but less powerful than a server in regular computing. They are capable of high-resolution and three-dimensional interfaces, and typically used to perform scientific and engineering work. Like server computers, they are often connected with other workstations. The main form-factor for this class
3248-783: A set of interlocking wood blocks. One of Raskin's instruments was the organ. In 1978 he published an article in BYTE on using computers with the instrument. Raskin published a paper highly critical of pseudoscience in nursing, such as therapeutic touch and Rogerian science , wherein he said: "Unlike science, nursing theory has no built-in mechanisms for rejecting falsehoods, tautologies, and irrelevancies." Jef Raskin married Linda S. Blum in 1982. They had three children together— Aza , Aviva, and Aenea, with honorary surrogate siblings R. Fureigh and Jenna Mandis. In 1985, Raskin described his house as "practically one large playground", with secret doors and passageways, an auditorium that seats 185, and
3360-504: A small CRT display and could be programmed in BASIC and APL . These were generally expensive specialized computers sold for business or scientific uses. Apple II , TRS-80 and Commodore PET were first generation personal home computers launched in 1977, which were aimed at the consumer market – rather than businessmen or computer hobbyists. Byte magazine referred to these three as the "1977 Trinity" of personal computing. Throughout
3472-478: A stand-alone desktop computer. The HP 9800 series , which started out as programmable calculators in 1971 but was programmable in BASIC by 1972, used a smaller version of a minicomputer design based on ROM memory and had small one-line LED alphanumeric displays and displayed graphics with a plotter. The Wang 2200 of 1973 had a full-size cathode-ray tube (CRT) and cassette tape storage. The IBM 5100 in 1975 had

Later versions of the language utilized "typing amplification" in which only the first letter is typed and the computer provides the balance of the instruction eliminating typing errors. It was also the basis for programming classes taught by Raskin and Collins in the UCSD Visual Arts Department. Raskin curated several art shows including one featuring his collection of unusual toys, and presenting toys as works of art. During this period, he changed

An all-in-one (AIO) desktop computer integrates the system's internal components into the same case as the display, thus occupying a smaller footprint (with fewer cables) than desktops that incorporate a tower. The All-in-one systems are rarely labeled as desktop computers. In personal computing ,

Apple sold a total of approximately 10,000 Lisa machines at US$ 9,995 (equivalent to about $ 30,600 in 2023) each, generating total sales of $ 100 million against a development cost of more than $ 150 million . The largest Lisa customer was NASA , which used LisaProject for project management. The Lisa 2 and its Mac ROM -enabled Macintosh XL version are the final two releases in
5264-693: The Macintosh project at Apple in the late 1970s. Jef Raskin was born in New York City to a secular Jewish family, whose surname is a matronymic from "Raske", Yiddish nickname for Rachel. He received a BA in mathematics and a BS in physics with minors in philosophy and music from Stony Brook University . In 1967, he received a master's degree in computer science from Pennsylvania State University , after having switched from mathematical logic due to differences of opinion with his advisor. Even though he had completed work typical for

He later hired his former student Bill Atkinson from UCSD to Apple, along with Andy Hertzfeld and Burrell Smith from the Apple Service Department, which was located in the same building as the Publications Department. Secretly bypassing Jobs's ego and authority by continually securing permission and funding directly at the executive level, Raskin created and solely supervised
5488-588: The Macintosh Plus was introduced in 1986. The Lisa operating system features protected memory , enabled by a crude hardware circuit compared to the Sun-1 workstation (c. 1982), which features a full memory management unit. Motorola did not have an MMU (memory-management unit) for the 68000 ready in time, so third parties developed their own. Apple's is also the result of a cost-cutting compromise, with sluggish performance. Based, in part, on elements from

Steve Wozniak , who around then had been co-leading the Macintosh team with Raskin, was on hiatus from the company following a traumatic airplane accident, allowing Jobs to take managerial lead over the project. Raskin is credited as one of the first to introduce Jobs and the Lisa engineers to

8064-574: The company, because there was such an antiacademic bias in the early Apple days." From his responsibility for documentation and testing, Raskin had great influence on early engineering projects. Because the Apple II only displayed uppercase characters on a 40-column screen, his department used the PolyMorphic Systems 8813 (an Intel-8080-based machine running a proprietary operating system called Exec) to write documentation; this spurred
8176-440: The completed TV advertisement at launch, only allowed the Cat to be sold by its typewriter sales people, and prevented Raskin from selling the Cat directly with a TV demonstration of how easy it was to use. Shortly thereafter, the stock market crash of 1987 so panicked Information Appliance's venture capitalists that they drained millions of dollars from the company, depriving it of the capital needed to be able to manufacture and sell
8288-493: The debut of their Apple II personal computer at the first West Coast Computer Faire . Jobs hired Raskin's company Bannister and Crun to write the Apple II BASIC Programming Manual. Raskin said "I was talking fifty dollars a page. They talked fifty dollars for the whole manual." Upon the Apple II unit with the serial number of "2", he reportedly wrote "a literate manual that became a standard for
8400-750: The desktop is that (apart from environmental concerns ) power consumption is not as critical as in laptop computers because the desktop is exclusively powered from the wall socket. Desktop computers also provide more space for cooling fans and vents to dissipate heat, allowing enthusiasts to overclock with less risk. The two large microprocessor manufacturers, Intel and AMD , have developed special CPUs for mobile computers (i.e. laptops) that consume less power and lower heat, but with lower performance levels. Laptop computers, conversely, offer portability that desktop systems (including small form factor and all-in-one desktops) cannot due to their compact size and clamshell design . The laptop's all-in-one design provides
8512-477: The development of an 80-column display card and a suitable text editor for the Apple II. His experiences testing Applesoft BASIC inspired him to design a competing product, called Notzo BASIC, which was never implemented. When Wozniak developed the first disk drives for the Apple II, Raskin went back to his contacts at UCSD and encouraged them to port the UCSD P-System operating system (incorporating
8624-561: The display screen placed on top, thus saving space on the user's actual desk, although these cases had to be sturdy enough to support the weight of CRT displays that were widespread at the time. Over the course of the 1990s, desktop cases gradually became less common than the more-accessible tower cases that may be located on the floor under or beside a desk rather than on a desk. Not only do these tower cases have more room for expansion, they have also freed up desk space for monitors which were becoming larger every year. Desktop cases, particularly
8736-463: The firm that eventually became IDEO. Bruce Daniels was in charge of applications development, and Larry Tesler was in charge of system software. The user interface was designed in six months, after which the hardware, operating system, and applications were all created in parallel. In 1982, Steve Jobs was forced out of the Lisa project, and he appropriated Jef Raskin 's existing Macintosh project. Raskin had conceived and led Macintosh since 1979 as
8848-470: The help of Sun Remarketing, Apple disposed of approximately 2,700 unsold Lisa units in a guarded landfill in Logan, Utah , to receive a tax write-off on the unsold inventory. Some leftover Lisa computers and spare parts were available until Cherokee Data (which purchased Sun Remarketing) went out of business. The Lisa was first introduced on January 19, 1983. It is one of the first personal computer systems with
8960-467: The highest level of shipments the PC market has seen since 2012. In addition, gaming desktops have seen a global revenue increase of 54% annually. For gaming the global market of gaming desktops, laptops, and monitors is expected to grow to 61.1 million shipments by the end of 2023, up from 42.1 million, with desktops growing from 15.1 million shipments to 19 million. PC gaming as a whole accounts for 28% of
9072-427: The late 2000s, and then the higher-performance Ultrabooks from 2011 onwards), which manufacturers believed had more potential to revive the PC market than desktops. In April 2017, StatCounter declared a "Milestone in technology history and end of an era" with the mobile Android operating system becoming more popular than Windows (the operating system that made desktops dominant over mainframe computers ). Windows
9184-602: The lower-priced Macintosh also hindered Lisa's acceptance. In 1982, after Steve Jobs was forced out of the Lisa project by Apple's board of directors, he appropriated the Macintosh project from Jef Raskin , who had conceived it as a sub- $ 1,000 (equivalent to $ 4,200 in 2023) text-based appliance computer in 1979. Jobs immediately redefined Macintosh to be graphical, but as a less expensive and more focused alternative to Lisa. Macintosh's launch in January 1984 quickly surpassed Lisa's underwhelming sales. Jobs began assimilating increasing numbers of Lisa staff, as he had done with
9296-618: The mind". According to Raskin Center, "Cognetics brings interface design out of the mystic realm of guruism, transforming it into an engineering discipline with a rigorous theoretical framework." The term cognetics had earlier been coined and trademarked by Charles Kreitzberg in 1982 when he started Cognetics Corporation , one of the first user experience design companies. It is also used to describe educational programs intended to foster thinking skills in grades 3-12 (US) and for Cognetics, Inc., an economic research firm founded by David L. Birch ,
9408-412: The mobile side. The post-PC trend saw a decline in the sales of desktop and laptop PCs. The decline was attributed to increased power and applications of alternative computing devices, namely smartphones and tablet computers. Although most people exclusively use their smartphones and tablets for more basic tasks such as social media and casual gaming , these devices have in many instances replaced
9520-542: The most important person in the development of the computer's hardware until the machine went into production, at which point he became the technical lead for the entire Lisa project. The hardware development team was headed by Robert Paratore. The industrial design, product design, and mechanical packaging were headed by Bill Dresselhaus, the Principal Product Designer of Lisa, with his team of internal product designers and contract product designers from
9632-552: The motherboard. While desktops have long been the most common configuration for PCs, by the mid-2000s the growth shifted from desktops to laptops. Notably, while desktops were mainly produced in the United States, laptops had long been produced by contract manufacturers based in Asia, such as Foxconn . This shift led to the closure of the many desktop assembly plants in the United States by 2010. Another trend around this time
9744-534: The much less expensive Mac. The Macintosh project assimilated a lot more Lisa staff. The final revision, the Lisa 2/10, was modified and sold as the Macintosh XL . The high cost and the delays in its release date contributed to the Lisa's discontinuation although it was repackaged and sold at $ 4,995 , as the Lisa 2. In 1986, the entire Lisa platform was discontinued. In 1987, Sun Remarketing purchased about 5,000 Macintosh XLs and upgraded them. In 1989, with
9856-438: The name was an acronym for "Local Integrated Software Architecture". Because Steve Jobs's first daughter was named Lisa (born in 1978), it was sometimes inferred that the name also had a personal association, and perhaps that the acronym was a backronym contrived later to fit the name. Andy Hertzfeld said that the acronym was reverse-engineered from the name "Lisa" in late 1982 by the Apple marketing team after they had hired
9968-476: The next several decades. The column-based interface , for instance, utilized by Mac OS X, had originally been developed for Lisa. It had been discarded in favor of the icon view. Apple's culture of object-oriented programming on Lisa contributed to the 1988 conception of Pink , the first attempt to re-architect the operating system of Macintosh. In 1989, after Wayne Rosing had moved to Sun Microsystems , he reflected on his time at Apple, recalling that building
10080-429: The original Macintosh, the Lisa has expansion slots. The Lisa 2 motherboard has a very basic backplane with virtually no electronic components, but plenty of edge connector sockets and slots. There are two RAM slots, one CPU upgrade slot, and one I/O slot, all in parallel. At the other end are three Lisa slots in parallel. In January 1985, following the Macintosh, the Lisa 2/10 (with integrated 10 MB hard drive)
10192-445: The press was full of intentionally-leaked rumors about a fall release of a 'baby Lisa' that would work in much the same way, only faster and cheaper. Its name: Macintosh." Lisa was launched on January 19, 1983. Its low sales were quickly surpassed by the January 1984 launch of the Macintosh. Newer versions of the Lisa were introduced that addressed its faults and lowered its price considerably, but it failed to achieve sales comparable to
10304-400: The project evolved into the " window-and-mouse-driven " form of its eventual release. Trip Hawkins and Jef Raskin contributed to this change in design. Apple's co-founder Steve Jobs was involved in the concept. At Xerox's Palo Alto Research Center (PARC), research had already been underway for several years to create a new humanized way to organize the computer screen, which became known as
10416-502: The replacement of PCs in the 1990s, but this slowed in the 2000s due to the poor reception of Windows Vista over Windows XP. IDC analyst Jay Chou suggested that Windows 8 actually hurt sales of PCs in 2012, as businesses decided to stick with Windows 7 rather than upgrade. Some suggested that Microsoft had acknowledged "implicitly ringing the desktop PC death knell" as Windows 8 offered little upgrade in desktop PC functionality over Windows 7; instead, Windows 8's innovations were mostly on
10528-453: The slogan on the Macintosh group's easel, "It's better to be a pirate than to join the Navy." Apple acknowledged Raskin's role after he had left the company by gifting him the millionth Macintosh computer, with an engraved brass plaque on the front. Raskin left Apple in 1982 and formed Information Appliance, Inc. to implement the concepts of his original Macintosh concept. The first product
10640-548: The spare parts and extensions tend to be standardized, resulting in lower prices and greater availability. For example, the size and mounting of the motherboard are standardized into ATX , microATX , BTX or other form factors . Desktops have several standardized expansion slots , like conventional PCI or PCI Express , while laptops tend to have only one mini-PCI slot and one PC Card slot (or ExpressCard slot). Procedures for assembly and disassembly of desktops tend to be simple and standardized as well. This tends not to be
10752-501: The spelling of his name from "Jeff" to "Jef" after having met Jon Collins and liking the lack of extraneous letters. Raskin occasionally wrote for computer publications, such as Dr. Dobb's Journal . He formed a company named Bannister and Crun, which was named for two characters playing in the BBC radio comedy The Goon Show . Raskin first met Apple Computer co-founders Steve Jobs and Steve Wozniak in their garage workshop following
10864-468: The start to be easy to use. In Computers by the Millions , he stated that expandable computers like the Apple II were too complex, and development was difficult due to the unknown nature of the machine the program ran on. The machine he envisioned was very different from the Macintosh that was eventually released and had much more in common with PDAs than modern desktop -based machines. Raskin started
10976-451: The supplier, hiring specially trained personnel, or at least, a much steeper learning curve to maintain and operate. Earlier GUI-controlled personal computers were not mass-marketed; for example, Xerox PARC manufactured its Alto workstation only for Xerox and select partners from the early to mid-1970s. Development of project "LISA" began in 1978. It underwent many changes and shipped at US$ 9,995 (equivalent to $ 30,600 in 2023) with
11088-583: The total gaming market as of 2017. This is partially due to the increasing affordability of desktop PCs. Full-sized desktops are characterized by separate display and processing components. These components are connected to each other by cables or wireless connections . They often come in a tower form factor. These computers are easy to customize and upgrade per user requirements, e.g. by expansion card . Early extended-size (significantly larger than mainstream ATX case) tower computers sometimes were labeled as " deskside computers ", but currently this naming
11200-414: The type of computers most commonly used were minicomputers , which, despite the name, were rather large and were "mini" only compared to the so-called " big iron ". Early computers, and later the general purpose high throughput " mainframes ", took up the space of a whole room. Minicomputers , on the contrary, generally fit into one or a few refrigerator-sized racks, or, for the few smaller ones, built into
11312-540: The user simply started typing text it switched into editor mode, and if numbers are typed it switched to calculator mode. In many cases these switches were largely invisible to the user. It was clear that Macintosh was the most interesting thing at Apple—and Steve Jobs took it over. Jef Raskin In 1981, after the Lisa team had "kicked him out", Steve Jobs 's attention drew toward Raskin's Macintosh project, intending to combine
11424-714: The very high price point, led to the failure of the Lisa in the marketplace. NASA purchased Lisa machines, mainly to use the LisaProject program. In 2018, the Computer History Museum announced it would be releasing the source code for Lisa OS, following a check by Apple to ensure this would not impact other intellectual property. For copyright reasons, this release does not include the American Heritage dictionary. For its 40th anniversary on January 19, 2023, Lisa OS Software version 3.1's source code
11536-405: The work of his colleagues in various companies and universities. At the start of the new millennium, Raskin undertook the building of a new computer interface based on his 30 years of work and research, called The Humane Environment, THE. On January 1, 2005, he renamed it Archy . It is a system incarnating his concepts of the humane interface, by using open source elements within his rendition of
11648-461: The young industry". In January 1978, Raskin joined Apple as Manager of Publications, the company's 31st employee. For some time he continued as Director of Publications and New Product Review, and also worked on packaging and other issues. He had concealed his degree in computer science, out of concern for cultural bias against academia among the hobby-driven personal computer industry. He explained, "If they had known ... they might not have let me in
11760-547: Was "Creator of Macintosh computer at Apple Computer, Inc." Raskin conceived and solely supervised the Macintosh project for approximately its first year; however, Hertzfeld describes Raskin's relationship to the drastically different finished Mac product more like that of an "eccentric great uncle" than its father. In Jobs's "Lost Interview" from 1996, he refers to the Macintosh as a product of team effort while acknowledging Raskin's early role. Jobs reportedly co-opted some of Raskin's leadership philosophies, such as when he wrote
11872-434: Was an accomplished archer , target shooter, bicycle racer and an occasional model race car driver. He was a musician and composer, publishing a series of collected recorder studies using the pseudonym of Aabel Aabius. In his later years he also wrote freelance articles for Macintosh magazines, such as Mac Home Journal , and many modeling magazines, Forbes , Wired , and computing journals. One of his favorite pastimes
11984-536: Was named for my daughter." The project began in 1978 as an effort to create a more modern version of the then-conventional design epitomized by the Apple II . A ten-person team occupied its first dedicated office at 20863 Stevens Creek Boulevard next to the Good Earth restaurant, and nicknamed "the Good Earth building". Initial team leader Ken Rothmuller was soon replaced by John Couch , under whose direction
12096-434: Was re-branded MacWorks XL as the primary system application, to convert the Lisa into the Macintosh XL . The launch version of Lisa Office System can not be used for programming, requiring the separate development OS called Lisa Workshop to be toggled and booted. Lisa Workshop was also used to develop Macintosh software for its first few years, until a Macintosh-native development system was released. For most of its lifetime,
12208-496: Was rebranded as Macintosh XL. It was given a hardware and software kit, enabling it to reboot into Macintosh mode and positioning it as the high-end Macintosh. The price was lowered yet again, to $ 4,000, and sales tripled, but CEO John Sculley said that Apple would have lost money increasing production to meet the new demand. Apple discontinued the Macintosh XL, leaving an eight-month void in Apple's high-end product line until
12320-470: Was similar in power to the Apple II and included a small 9-inch (230 mm) black-and-white character display and floppy drive, in a small case. It was text only, as Raskin disliked the computer mouse or anything else that could take his hands from the keyboard. Several basic applications were built into the machine, selectable by pressing function keys. The machine included logic to understand user intentions and switch programs dynamically. For instance, if
12432-449: Was the increasing proportion of inexpensive base-configuration desktops being sold, hurting PC manufacturers such as Dell whose build-to-order customization of desktops relied on upselling added features to buyers. Battery-powered portable computers had just a 2% worldwide market share in 1986. However, laptops have become increasingly popular, both for business and personal use. Around 109 million notebook PCs shipped worldwide in 2007,
12544-402: Was to play music with his children. He accompanied them on the piano while they played or sang while going through old fake-books passed down from his father. They routinely improvised together. Raskin owned Jef's Friends, a small company which made model airplane kits. He was a toy designer. He designed Space Expander, a hanging cloth maze for a person to walk through. He designed Bloxes,
