Proteus system diagram. This diagram was actually a copy of the Proteus III sold in kit form by the French magazine Microsystème, and called Microsystème 1.\
|
|
More information, as well as the binary content of the 8 BASIC EPROMs can be downloaded here.\
|
|
Thanks to M. Lahaye from Belgium who sent us this information along with the following comment:\
|
|
*Eprom1 to eprom8 is the binary content. It is orininaly delivered on 8 EPROMs of 1 Kbytes (27808). A hard error of tangent is present so I fix it but I must limit the length of the presentation message to recover a few bytes. It is the eprom 1b and 8b.*\
|
|
*The pdf is the 3 pages of the magazine with the first article. This is enough if someone want to rebuilt the system as you will find the i/o addresses.*

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](/museum/apple-ii/), [Commodore PET](/museum/commodore-pet-2001/) and [Tandy TRS-80 Model I](/museum/tandy-radio-shack-trs-80-model-i/).
