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 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 Tandy 1000 was the first in a series of IBM PC compatible home computers produced by the Tandy Corporation, sold through its Radio Shack and Radio Shack Computer Center stores. Introduced in 1984, the Tandy 1000 line was designed to offer affordable yet capable systems for home computing and education. Tandy-specific features, such as enhanced graphics, sound, and a built-in joystick port, made the computers particularly attractive for home use.
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%.
The Apple IIe Card is a compatibility card, which through hardware and software emulation, allows certain Macintosh computers to run software designed for the Apple II. Released in March 1991 for use with the LC family, Apple targeted the card at its widely dominated educational market to ease the transition from Apple II-based classrooms, with thousands of entrenched educational software titles, to Macintosh-based classrooms.
Tiki-100 was a desktop home/personal computer manufactured by Tiki Data of Oslo, Norway. The computer was launched in the spring of 1984 under the original name Kontiki-100, and was first and foremost intended for the emerging educational sector, especially for primary schools. Early prototypes had 4 KB ROM, and the '100' in the machine's name was based on the total KB amount of memory.
The Apple IIGS is a 16-bit personal computer produced by Apple Computer. It is the fifth and most powerful of the Apple II family. It is compatible with earlier Apple II models, but has a Macintosh look and feel, and resolution and color similar to the Amiga and Atari ST. The "GS" in the name stands for "Graphics and Sound", referring to its enhanced multimedia hardware, especially its state-of-the-art audio.
The Apple IIc is a personal computer introduced by Apple Inc. shortly after the launch of the original Macintosh in 1984. It is essentially a compact and portable version of the Apple IIe. The IIc has a built-in floppy disk drive and a keyboard, and was often sold with its matching monitor. The c in the name stands for compact, referring to the fact it is a complete Apple II setup in a smaller notebook-sized housing. It is compatible with a wide range of Apple II software and peripherals.
The Micro-Professor MPF-I is a microcomputer released by Multitech in 1981. The company's first branded product, it was marketed as a training system to learn machine code and assembly language for the Zilog Z80 microprocessor. After releasing several iterations of the product, Acer sold the product line to Flite Electronics in 1993.
The Rainbow 100 is a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982. This desktop unit had a monitor similar to the VT220 and a dual-CPU box with both 4 MHz Zilog Z80 and 4.81 MHz Intel 8088 CPUs. The Rainbow 100 was a triple-use machine: VT100 mode, 8-bit CP/M mode, and CP/M-86 or MS-DOS mode using the 8088. It ultimately failed to succeed in the marketplace which became dominated by the simpler IBM PC and its clones which established the industry standard as compatibility with CP/M became less important than IBM PC compatibility. Writer David Ahl called it a disastrous foray into the personal computer market. The Rainbow was launched along with the similarly packaged DEC Professional and DECmate II which were also not successful. The failure of DEC to gain a significant foothold in the high-volume PC market would be the beginning of the end of the computer hardware industry in New England, as nearly all computer companies located there were focused on minicomputers for large organizations, from DEC to Data General, Wang, Prime, Computervision, Honeywell, and Symbolics Inc.
Micro-Professor II (MPF-II) is an Apple II clone introduced in 1982 by Multitech. It is Multitech second branded computer product and also one of the earliest Apple II clones. The MPF II doesn't look like most other computers, with its case being a slab with a small chiclet keyboard on the lower part.
The ATM Turbo, also known simply as ATM is a ZX Spectrum clone, developed in Moscow in 1991, by two firms, MicroArt and ATM.
The Memotech MTX500 and MTX512 are a range of 8-bit Zilog Z80A based home computers released by the British company Memotech in 1983 and sold mainly in the UK, France, Germany and Scandinavia. Originally a manufacturer of memory add-ons for Sinclair machines, Memotech developed their own competing computer when it was perceived the expansion pack business would no longer be viable.
The Mac286 was an Intel 80286-based MS-DOS coprocessor expansion card for one of Apple Computer's first expandable Macintosh computers, the 1987 Macintosh II. It was developed by Phoenix Technologies under contract to Apple Computer and sold by AST Research in an effort to close the gap between the Macintosh and IBM PC computing worlds. AST also introduced the related Mac86 card for the Macintosh SE.
The Apple II Plus is the second model of the Apple II series of personal computers produced by Apple Computer. It was sold from June 1979 to December 1982. Approximately 380,000 II Pluses were sold during its four years in production before being replaced by the Apple IIe in January 1983.
The TRS-80 Model II is a computer system launched by Tandy in October 1979, and targeted at the small-business market. It is not an upgrade of the original TRS-80 Model I, but a new system.
The West PC-800 was a home computer introduced by Norwegian company West Computer AS in 1984. The computer was designed as an alarm center allowing use of several CPUs and operating systems. The company introduced an IBM PC compatible in early 1986 and the West PC-800 line was phased out.
The Dimension 68000 is a microcomputer introduced by the Micro Craft Corporation in 1983 that sought to emulate the Apple II, the IBM PC, and various CP/M-centric computers through a family of coprocessor expansion cards and emulation software. The Dimension 68000 can also run as a standalone computer based on the Motorola 68000 from which it gets its namesake. The computer is mostly the brainchild of Mike Carpenter, a former executive of a scientific instrument manufacturer who incorporated Micro Craft in Dallas, Texas, to develop the Dimension 68000. It had a market lifespan of three years and received mixed, mostly positive, reception from the technology press. Criticism was leveled at the $6,250 price tag for the computer with the full deck of coprocessor cards, as well as the extent of the emulation power of those cards.
The TK 2000 microcomputer, produced by the Brazilian company Microdigital Eletrônica Ltda, was presented to the public during the 1983 Computer Fair and launched in 1984. It was a clone of the Microprofessor II manufactured by Multitech. Based on the 6502 CPU, the machine was partially compatible with Apple II Plus software and hardware. Some software was developed specifically for the machine, including productivity programs and games.
