Apple Lisa
Lisa is a desktop computer developed by Apple, produced from January 19, 1983 to August 1, 1986, and succeeded by Macintosh. It was the first mass-market personal computer operable through a graphical user interface. 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 the supplier, hiring specially trained personnel, or at least, a much steeper learning curve to maintain and operate.
Development of project "LISA" began in 1978. It underwent many changes and shipped at with a five-megabyte hard drive. It was affected by its high price, insufficient software, unreliable FileWare 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 a document-oriented workflow. The hardware is more advanced overall than the following Macintosh, including hard disk drive support, up to 2 megabytes of random-access memory, 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 the ad hoc protected memory implementation, due to the lack of a Motorola memory management unit. Cost-cutting measures that target the consumer market, and the delayed availability of the 68000 processor and its impact on the design process, made the user experience sluggish. The workstation-tier high price and lack of a technical software application library made it a difficult sale for all markets. The IBM PC's popularity and Apple's decision to compete with itself through the lower-priced Macintosh also hindered Lisa's acceptance.
In 1981, 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- 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 the Apple II division upon taking Raskin's project. Newer Lisa models addressed its shortcomings but, even with a major price reduction, the platform failed to achieve sales volumes comparable to the much less expensive Mac. The Lisa 2/10 is the final model, then rebranded as the high-end Macintosh XL.

Development
Name
Though the original documentation only refers to it as "The Lisa", Apple officially stated that the name was an acronym for "Local Integrated Software Architecture". Because Steve Jobs's first daughter was named Lisa, 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 a marketing consultancy firm to find names to replace "Lisa" and "Macintosh" and then rejected all of the suggestions. 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 was named for my daughter."Research and design
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 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, research had already been underway for several years to create a new humanized way to organize the computer screen, which became known as the desktop metaphor. Steve Jobs visited PARC in 1979 and was absorbed and excited by the revolutionary mouse-driven GUI of the Alto. By late 1979, Jobs successfully negotiated a sale of Apple stock to Xerox, in exchange for his Lisa team receiving two demonstrations of ongoing research projects at PARC. When the Apple team saw the demonstration of the Alto computer, they were able to see in action the basic elements of what constituted a workable GUI. The Lisa team put a great deal of work into making the graphical interface a mainstream commercial product.
The Lisa was a major project at Apple, which reportedly spent more than on its development. More than 90 people participated in the design, plus more in the sales and marketing effort, to launch the machine. BYTE magazine credited Wayne Rosing with being 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 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 1980, 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 a text-based appliance computer. Jobs redefined Macintosh as a cheaper and more usable form of Lisa's concepts, and led the skunkworks project with substantial motivation to compete in parallel with the Lisa team.
In September 1981, below the announcement of the IBM PC, InfoWorld reported on Lisa, "McIntosh", and another Apple computer secretly under development "to be ready for release within a year". It described Lisa as having a 68000 processor and 128KB RAM, and "designed to compete with the new Xerox Star at a considerably lower price". In May 1982, the magazine reported that "Apple's yet-to-be-announced Lisa 68000 network work station is also widely rumored to have a mouse." BYTE reported similar rumors that month.
Launch
Lisa was announced on January 19, 1983. By then, the press discussed rumors of Macintosh as a much less-expensive Apple computer with similar functionality, perhaps planned for late 1983. Apple Confidential said, "Even before the Lisa began shipping in June, 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's 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 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.Discontinuation
The high cost and the delays in its release date contributed to the Lisa's discontinuation although it was repackaged and sold at, 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 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 went out of business.
Overview
Hardware
The Lisa was first introduced on January 19, 1983. It is one of the first personal computer systems with a graphical user interface 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 is defined as 1980; the software won't accept any value below 1981, so the only valid range is 1981–1995. The real-time clock depends on a NiCd pack of batteries that only lasts for a few hours when main power is not present. Prone to failure over time, the battery packs could leak corrosive alkaline electrolyte and ruin the circuit boards.
The integrated monochrome black-on-white monitor has rectangular pixels on a 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 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.
