The Thomson TO7, also called Thomson 9000[1] is 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.[2]
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.[1] 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.
