The Apple II graphics were composed of idiosyncratic modes and settings that could be exploited.
 This graphics system debuted on the original Apple II, continued with the Apple II Plus and was carried forward and expanded with the Apple IIe, Enhanced IIe, IIc, IIc Plus and II.
Star Trek: The Kobayashi Alternative was a "Star Trek" themed computer software game, designed for the Apple II Plus, Apple IIe, and Apple IIc.
 The game was also available for the Commodore 64, Macintosh and IBM PC.
 This text adventure was first published in 1985 by Simon & Schuster.
 The player assumes the role of Captain James T. Kirk.
 As Kirk, the player commands the actions of the "Enterprise" crew, as well as the "Enterprise" itself.
 The game was expansive and ambitious, but also very buggy .
The Macintosh IIcx is a personal computer designed, manufactured and sold by Apple Computer, Inc. from March 1989 to March 1991.
 Introduced half a year after the Macintosh IIx, the IIcx resembled the IIx to a great extent and provided the same performance, but was quieter (due to its quieter fan on a smaller power supply) than its predecessor.
 Reducing the number of NuBus slots from 6 to 3 also made the machine much more compact.
 The new case, Apple's first to be designed to operate in either a horizontal or vertical orientation, remained in use for its successors the IIci and Quadra 700.
 The idea for vertical orientation, one of the first minitower cases, was suggested by Apple CEO John Sculley, who was running out of space on his desk, despite the fact that the new layout actually took more space once the monitor was taken into account.
 The model was designated IIcx for "compact" (echoing the earlier Apple IIc compact model in the Apple II series), and the "x" was Apple's designation for the 68030 processor.
The Apple IIc, the fourth model in the Apple II series of personal computers, is Apple Computer’s first endeavor to produce a portable computer.
 The result was a 7.5 lb notebook-sized version of the Apple II that could be transported from place to place.
 The "c" in the name stood for "compact", referring to the fact it was essentially a complete Apple II computer setup (minus display and power supply) squeezed into a small notebook-sized housing.
 While sporting a built-in floppy drive and new rear peripheral expansion ports integrated onto the main logic board, it lacks the internal expansion slots and direct motherboard access of earlier Apple IIs, making it a closed system like the Macintosh.
 However, that was the intended direction for this model — a more appliance-like machine, ready to use out of the box, requiring no technical know-how or experience to hook up and therefore attractive to first-time users.
Impossible Mission II is a 1988 computer game developed by Novotrade and published by Epyx.
 It was released for the Commodore 64, ZX Spectrum, Amstrad CPC, Enterprise 64 and 128, Nintendo Entertainment System, MS-DOS based PCs, Atari ST, Apple IIe with at least 128K, Apple IIc, Apple IIGS and Amiga computers.
 In 2004, it was one of the games featured on the C64 Direct-to-TV.
The DAI personal computer is a rare, early home computer from the Belgian company "Data Applications International".
 The DAI came to market in 1980.
 It provided many pioneering features such as high resolution color graphics, a maths co-processor, and a pre-compiling BASIC interpreter.
 But it never became a commercial success.
Open architecture is a type of computer architecture or software architecture that is designed to make adding, upgrading and swapping components easy.
 For example, the IBM PC and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc and Amiga 500 computers have a closed architecture.
 Open architecture systems may use a standardized system bus such as S-100, PCI or ISA or they may incorporate a proprietary bus standard such as that used on the Apple II, with up to a dozen slots that allow multiple hardware manufacturers to produce add-ons, and for the user to freely install them.
 By contrast, closed architectures, if they are expandable at all, have one or two "expansion ports" using a proprietary connector design that may require a license fee from the manufacturer, or enhancements may only be installable by technicians with specialized tools or training.
The Apple IIc Plus is the sixth and final model in the Apple II series of personal computers, produced by Apple Computer.
 The ""Plus"" in the name was a reference to the additional features it offered over the original portable Apple IIc, such as greater storage capacity (a built-in 3.5-inch floppy drive replacing the classic 5.25-inch drive), increased processing speed, and a general standardization of the system components.
 In a notable change of direction, the Apple IIc Plus, for the most part, did not introduce new technology or any further evolutionary contributions to the Apple II series, instead merely integrating existing peripherals into the original Apple IIc design.
 The development of the 8-bit machine was criticized by quarters more interested in the significantly more advanced 16-bit Apple II.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1980s.
 The 1981 launch of the IBM Personal Computer coined both the term "Personal Computer" and "PC".
 A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
 After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods.
 Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
Stan Veit (25 December 1919 - 29 July 2010) was an entrepreneur and publisher who played an important role in the early days of the personal computer industry in the United States.
 He ran "Computer Mart," the first computer store in New York City, was the personal computer editor of "Popular Electronics" Magazine, and then Editor-in-Chief of "Computer Shopper".
 He published his reminiscences about the early history of the personal computer industry in a 1993 book called "Stan Veit's History of the Personal Computer."
