The Thomson TO7, also called Thomson 9000is a home computer introduced by Thomson SA in November 1982, with an original retail price of 3750 Franc. By 1983 over 40000 units were produced.
The TO7 is built around a 1 MHz Motorola 6809 processor. ROM cartridges, designed as MEMO7, can be introduced through a memory bay. The user interface uses Microsoft BASIC, included in the kit cartridge. The keyboard features a plastic membrane, and further user input is obtained through a lightpen. Cooling is provided by a rear radiator. Standard TV screens can be used as output through a SCART (Peritel) connector, with a resolution of 320x200 (with 2 colors for each 8x1 pixels).
An upgraded version, the Thomson TO7/70, was released in 1984.Among improvements was an increased RAM of 48KB (64 KB including Video RAM) instead of 8KB (22 KB including video RAM). 70 stands for 64+6 (64KB RAM + 6KB ROM). The 6809 processor was replaced by a 6809E and the color palette was extended from 8 to 16 colors.

The Amstrad CPC is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the Sinclair ZX Spectrum, where it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe.
The Apple II is an 8-bit home computer and one of the world's first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak. It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire and was the first consumer product sold by Apple Computer, Inc. It is the first model in a series of computers which were produced until Apple IIe production ceased in November 1993. The Apple II marks Apple's first launch of a personal computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists.
The Commodore 64, also known as the C64 or the CBM 64, is an 8-bit home computer introduced in January 1982 by Commodore International. It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes(65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.
The Neo Geo, stylised as NEO・GEO, also written as NEOGEO, is a cartridge-based arcade system board and fourth-generation home video game console released on April 26, 1990, by Japanese game company SNK Corporation. It was the first system in SNK's Neo Geo family. The Neo Geo was marketed as 24-bit; its CPU is technically a 16/32-bit 68000-based system with an 8/16-bit Z80 coprocessor, while its GPU chipset has a 24-bit graphics data bus.
The RadioShack TRS-80 Color Computer is a line of home computers based on the Motorola 6809 processor. The Tandy Color Computer line started in 1980 with what is now called the CoCo 1 and ended in 1991 with the more powerful CoCo 3. All three CoCo models maintained a high level of software and hardware compatibility, with few programs written for the older model being unable to run on the newer ones.
The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 and manufactured until 1992. All of the machines in the family are technically similar and differ primarily in packaging. They are based on the MOS Technology 6502 CPU running at 1.79 MHz, and were the first home computers designed with custom co-processor chips. This architecture enabled graphics and sound capabilities more advanced than most contemporary machines, and gaming on the platform was a major draw. The first-person space combat simulator Star Raiders is considered the platform's killer app. The systems launched with a series of plug and play peripherals that used the Atari SIO serial bus system, an early analog of USB.
The Commodore 128, also known as the C128, C-128, C= 128, is the last 8-bit home computer that was commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the bestselling Commodore 64.
The VIC-20 is an 8-bit home computer that was sold by Commodore Business Machines. The VIC-20 was announced in 1980, roughly three years after Commodore's first personal computer, the PET. The VIC-20 was the first computer of any description to sell one million units. It was described as "one of the first anti-spectatorial, non-esoteric computers by design...no longer relegated to hobbyist/enthusiasts or those with money, the computer Commodore developed was the computer of the future."
The Commodore PET is a line of home/personal computers produced starting in 1977 by Commodore International. The system combined a MOS 6502 microprocessor, Commodore BASIC in read only memory (ROM), a keyboard, a computer monitor and a cassette deck for data and program storage in a single all-in-one case. The name was suggested by Andre Souson after he saw the Pet Rock in Los Gatos, and stated they were going to make the "pet computer".
The Apple IIGS, the fifth and most powerful of the Apple II family, is a 16-bit personal computer produced by Apple Computer, Inc. While featuring the Macintosh look and feel, and resolution and color similar to the Commodore Amiga and Atari ST, it remains compatible with earlier Apple II models. The "GS" in the name stands for "Graphics and Sound," referring to its enhanced multimedia hardware, especially its state-of-the-art audio.
The Commodore Plus/4 is a home computer released by Commodore International in 1984. The "Plus/4" name refers to the four-application ROM resident office suite ; it was billed as "the productivity computer with software built-in."
The VTech Laser 200 was an early 8-bit home computer from 1983, also sold as the Salora Fellow, the Seltron 200 in Hungary and Italy, the Smart-Alec Jr. by Dynasty Computer Corporation in Dallas, Texas for the USA, the Texet TX8000A, and the Dick Smith VZ 200 and the VTech VZ 200.
The ThomsonMO5 is a home computer introduced in France in 1984 to compete against systems such as the ZX Spectrum and Commodore 64. At the same time, Thomson also released the up-market Thomson TO7/70 machine. The MO5 was not sold in vast quantities outside France and was largely discontinued in favour of the improved Thomson MO6 in 1986. MO5s were also used as educational tools in French schools for a period.
The BBC Master is a home computer released by Acorn Computers in early 1986. It was designed and built for the British Broadcasting Corporation (BBC) and was the successor to the BBC Micro Model B. The Master 128 remained in production until 1993.

The NEC PC-6000 Series is a series of 8-bit home computers introduced in November 1981 by NEC Home Electronics (NEC-HE). There are several models in this series, such as the PC-6001, the PC-6001 MK2 and the PC-6001 MK2 SR. There is also an American version, called the NEC TREK, or NEC PC-6001A. It was followed by the PC-6600 Series.
The Twin Famicom is a home video game console that was produced by Sharp Corporation in 1986 and was only released in Japan. It is a licensed Nintendo product that combines the Family Computer (Famicom) and the Family Computer Disk System (FDS) into a single piece of hardware.
