The Thomson TO7, also called Thomson 9000[2] is a home computer introduced by Thomson SA in November 1982,[3] with an original retail price of 3750 FF.[4] By 1983 over 40000 units were produced.[4] About 84 games were released for the TO7.[5][6]
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. A standard television can serve as a monitor using a RGB SCART (Peritel) connector, with a resolution of 320x200 (with 2 colors for each 8 x 1 pixels).
The TO7 prototype, called Thomson T9000, was developed in 1980. The differences regarding the production model are a different startup menu and buggier BIOS.[7]
