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.[5] About 84 games were released for the TO7.[6][7]
The TO7 is built around a 1 MHzMotorola 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.[8]
The Thomson TO7 runs on a Motorola 6809 processor clocked at 1 MHz and features 22 KB of RAM (8 KB for the user, 8 KB used as video memory and 8K x 6 bits color memory) and 20KB of ROM (4KB for the monitor and 16KB on MEMO7 cartridges).[9]
As common on home computers designed to be connected to an ordinary TV screen, the 320 x 200 pixels active area doesn't cover the entire screen, and is surrounded by a border.[10] Graphics were limited to 8 colours (generated by combination of RGB primaries) with proximity constraints (2 colors for each 8 x 1 pixel area).[9][3] The video output is RGB on a SCART connector, with the refresh rate being 625-line compatible 50Hz.[9]
Audio featured a single channel sound generator with five octaves. A "game expansion" was capable of four channel, six octaves sound.[2]
The keyboard has 58 keys and includes arrow keys.[2]
Besides cartridges, the machine used cassette tapes for file storage.[2]
Thomson TO7/70
An upgraded version, the Thomson TO7/70, was released in 1984[11] with an introductory price of 3590 FF.[12] It was used as an educational tool in French schools under the Computing for All plan, where the TO7/70 could be used as a used a "nano-machine" terminal for the "Nanoréseau" educational network.[13]
Among improvements RAM was increased to 64 KB - "70" on the version name stands for 64+6 (64KB RAM + 6KB ROM).[14] The 6809 processor was replaced by a Motorola 6809E and the color palette was extended from 8 to 16 colors.[15]
Graphics were similar to the Thomson MO5[16] and generated by a Motorola MCA1300 gate array[1] capable of 40×25 text display and a resolution of 320 x 200 pixels with 16 colours (limited by 8 x 1 pixel colour attribute areas).[17][18] The colour palette is 4-bit RGBI, with 8 basic RGB colours and a intensity bit (called P for "Pastel") that controlled saturation ("saturated" or "pastel").[10][19]
Software developed for the TO-7 can be run on the TO-7/70, but the reverse is not possible.[11] At least three games were released for the TO7/70.[20]
