Home computers

The ZX Spectrum is an 8-bit home computer developed and marketed by Sinclair Research. One of the most influential computers ever made and one of the all-time bestselling British computers, with over five million units sold. It was released in the United Kingdom on 23 April 1982, and around the world in the following years, most notably in Europe, the United States, and Eastern Bloc countries.

Amiga is a family of personal computers produced by Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These include the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. The Amiga differs from its contemporaries through custom hardware to accelerate graphics and sound, including sprites, a blitter, and four channels of sample-based audio. It runs a pre-emptive multitasking operating system called AmigaOS.

The educational computer LC80 was a single-board computer manufactured in the German Democratic Republic (GDR) and intended for teaching purposes. It was the first computer that retail customers could buy in the GDR.

The APF Imagination Machine is a combination home video game console and home computer system released by APF Electronics Inc. in late 1979. It has two separate components, the APF-M1000 game system, and an add-on docking bay with full sized typewriter keyboard and tape drive. The APF-M1000 was built specifically to compete with the Atari 2600. The full APF Imagination Machine, including the APF-M1000 console and the IM-1 computer component, originally sold for around US$599 (equivalent to $2,600 in 2024).

The Grundy NewBrain was a line of microcomputers launched in 1982 by Grundy Business Systems Ltd of Teddington and Cambridge, England. A contemporary of the ZX80 and BBC Micro, the NewBrain was mostly used in business settings. It is notable for its chicklet keyboard and models that featured a one-line display, allowing them to be used as a portable computer, in addition to television output. Another unique feature of the system was NewBrain BASIC, a BASIC programming language that featured an on-the-fly compiler.

The Compukit UK101 microcomputer (1979) is a kit clone of the Ohio Scientific Superboard II single-board computer, with a few enhancements for the UK market - notably replacing the 24×24 (add guardband kit to give 32×32) screen display with a more useful 48×16 layout working at UK video frequencies. The video output is black and white with 256 semigraphic characters generated by a two kilobyte ROM. It has no bit-mapped graphics capability. The video is output through a UHF modulator, designed to connect to a TV set.

The Philips P2000T home computer was Philips' first real entry in the home computer market in 1980, after the Philips Videopac G7000 game system (better known in North America as the Magnavox Odyssey2) which they already sold to compete with the Atari 2600 and similar game systems. There was also a P2000M version with an additional 80-column text card for use with a monochrome monitor. This version shipped with a monitor cabinet also housing a dual 5¼-inch floppy disk drive. The P2000C version, introduced in 1982, was portable.

The Enterprise is a Zilog Z80-based home computer announced in 1983, but due to a series of delays, was not commercially available until 1985. It was developed by British company Intelligent Software and marketed by Enterprise Computers.

The Timex Sinclair 1000 (or T/S 1000) was the first computer produced by Timex Sinclair, a joint venture between Timex Corporation and Sinclair Research. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest home computer at the time; it was advertised as "the first computer under $100". The computer was aimed at regular home users. As purchased, the T/S 1000 was fully assembled and ready to be plugged into home televisions, which served as a video monitor. The T/S 1000 was a slightly modified version of the Sinclair ZX81 with an NTSC RF modulator, for use with North American TVs, instead of PAL for European TVs. The T/S 1000 doubled the onboard RAM from 1 KB to 2 KB; further expandable by 16 KB through the cartridge port. The T/S 1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the membrane keyboard, which had modified nomenclature to suit American tastes (e.g. "DELETE" instead of "RUBOUT") Just like the ZX81, the T/S 1000 had black-and-white graphics and no sound.

The Sinclair QL (for Quantum Leap) is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum.
