Proteus III

Little is known about this computer. Help welcomed.

The Proteus III was apparently made in France. It is powered by a Motorola 6800 CPU. There were two models : Proteus III A with 16 KB RAM, and Proteus III B with 32 KB RAM. There was even a third version (Proteus III C ?) with 48 KB RAM.

It can display 16 lines by 64 characters but has no specific graphical resolution, only semi-graphic characters which can be used to simulate graphics.

5.25'' disk-drives (Double Density) were available as an option. You could also connect a serial printer and tape recorder.

The extended Basic is stored in ROM and thus available as soon as the system is powered on. It has no edition feature but detect errors while typing commands.

It had apparently no great success as its main competitors were Apple II, Commodore PET and Tandy TRS-80 Model I.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).
