The Apple Computer 1 (Apple-1), later known predominantly as the Apple I, is an 8-bit motherboard-only personal computer designed by Steve Wozniak and released by the Apple Computer Company in 1976. The company was initially formed to sell the Apple I – its first product – and would later become the world's largest technology company. The idea of starting a company and selling the computer came from Wozniak's friend and Apple co-founder Steve Jobs. One of the main innovations of the Apple I was that it included video display terminal circuitry on its circuit board, allowing it to connect to a low-cost composite video monitor or television, instead of an expensive computer terminal, compared to most existing computers at the time. It and the Sol-20 were some of the first home computers to have this capability.
The Apple II series of microcomputers was initially designed by Steve Wozniak, manufactured by Apple Computer, and launched in 1977 with the Apple II model that gave the series its name. It was followed by the Apple II Plus, Apple IIe, Apple IIc, and Apple IIc Plus, with the 1983 IIe being the most popular. The name is trademarked with square brackets as Apple ][, then, beginning with the IIe, as Apple //. In terms of ease of use, features, and expandability, the Apple II was a major advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists.
The Apple III is a business-oriented personal computer produced by Apple Computer and released in 1980. Running the Apple SOS operating system, it was intended as the successor to the Apple II, but was largely considered a failure in the market. It was designed to provide key features business users wanted in a personal computer: a true typewriter-style upper/lowercase keyboard and an 80-column display.
The Apple II is a personal computer released by Apple Inc. in June 1977. It was one of the first successful mass-produced microcomputer products and is widely regarded as one of the most important personal computers of all time due to its role in popularizing home computing and influencing later software development.
The Power Macintosh, later Power Mac, is a family of personal computers designed, manufactured, and sold by Apple Computer, Inc as the core of the Macintosh brand from March 1994 until August 2006.
The TRS-80 Micro Computer System is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. It is one of the earliest mass-produced and mass-marketed retail home computers.
VisiCalc is the first spreadsheet computer program for personal computers, originally released for the Apple II by VisiCorp on October 17, 1979. It is considered the killer application for the Apple II, turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years later. More than 700,000 copies were sold in six years, and up to 1 million copies over its history.
A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's cathode-ray tube (CRT) display.
The Apple IIe is the third model in the Apple II series of personal computers produced by Apple Computer. It was released in January 1983 as the successor to the Apple II Plus. The e in the name stands for enhanced. It is the first Apple II with built-in lowercase and 80-column text support, as well as 64K RAM, while reducing the total chip count from previous models by approximately 75%.
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 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.
A screensaver is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors. Though most modern monitors are not susceptible to this issue, screensaver programs are still used for other purposes. Screensavers are often set up to offer a basic layer of security by requiring a password to re-access the device. Some screensaver programs also use otherwise-idle computer resources to do useful work, such as processing for volunteer computing projects.
The Commodore 1530 (C2N) Datasette, later also Datassette, is Commodore's dedicated magnetic-tape data storage device. Using compact cassettes as the storage medium, it provides inexpensive storage to Commodore's 8-bit computers, including the PET, VIC-20, and Commodore 64. A physically similar model, Commodore 1531, was made for the Commodore 16 and Plus/4 series computers.
The iMac G5 is a series of all-in-one personal computers that was designed, manufactured and sold by Apple Computer from 2004 to 2006. The iMac G5 returned to a more traditional design after the "sunflower" iMac G4, with the computer components fitted behind a liquid-crystal display and mounted on an aluminum foot. The computer was designed around the need to cool its PowerPC 970 processor, and features an interior divided into zones for cooler, quieter operation.
The ProFile is the first hard disk drive produced by Apple Computer, initially for use with the Apple III. The original model had a formatted capacity of 5 MB and connected to a special interface card that plugged into an Apple III slot. In 1983, Apple offered a ProFile interface card for the Apple II, with software support for Apple ProDOS and Apple Pascal.
The iMac G4 is an all-in-one personal computer designed, manufactured, and sold by Apple Computer from January 2002 to August 2004. The computer is comprised of a hemispheric base that holds the computer components, including the PowerPC G4 processor, with a flatscreen liquid-crystal display (LCD) mounted above. The display is connected to the base via a stainless steel arm that allows the monitor to be tilted and swiveled.
Apple Inc., originally Apple Computer, Inc., is a multinational corporation that creates and markets consumer electronics and attendant computer software, and is a digital distributor of media content. Apple's core product lines are the iPhone smartphone, iPad tablet computer, and the Mac personal computer. The company offers its products online and has a chain of retail stores known as Apple Stores. Founders Steve Jobs, Steve Wozniak, and Ronald Wayne created Apple Computer Co. on April 1, 1976, to market Wozniak's Apple I desktop computer, and Jobs and Wozniak incorporated the company on January 3, 1977, in Cupertino, California.
The Apple Monitor III is a 12-inch green phosphor (A3M0039) or white phosphor (A3M0006) CRT-based monochrome monitor manufactured by Sanyo and later Hitachi for Apple Computer; for the Apple III personal computer, introduced in 1980. As Apple's first monitor in their business line of machines, it preceded the Apple Monitor II by several years. The Apple Monitor III's main feature was the fine mesh on the CRT to reduce glare. It was also notable for having a very slow phosphor refresh, which adversely created a ghosting effect with any video movement. The Apple Monitor III was also compatible with the entire Apple II series and numerous other computers through its standard composite video input jack.
Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user. These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and programming.
Composite artifact colors is a designation commonly used to address several graphic modes of some 1970s and 1980s home computers. With some machines, when connected to an NTSC TV or monitor over composite video outputs, the video signal encoding allowed for extra colors to be displayed, by manipulating the pixel position on screen, not being limited by each machine's hardware color palette.
The Keyboard Company, Inc., was an American electronics company based in Garden Grove, California. It was contracted by Apple Computer to produce the keyboards of their microcomputers in the late 1970s and early 1980s. The company also produced a number of peripherals separately for Apple's systems. Apple acquired the company in 1982 and renamed it the Apple Accessory Products Division (APD).
