Thomson TO8
PredecessorThomson TO9

It's based on the Thomson TO8 and fully compatible with it. This also enables it to run Thomson MO6 software. The computer was designed to be used as a Minitel server and has a built-in V23 modem (with a speed of 1200/75 bauds). This feature was accessible under BASIC and from the communication software that came with the computer. The machine was sold with a word processing program (Paragraphe), a database (Fiches & Dossiers) and a spreadsheet (Multiplan).

Compared with the TO9, the TO9+ added:[4][5]

  • Basic 512
  • 512 KB RAM
  • double-sided floppy disk drive (640 kB)
  • integrated modem
  • two ports for mice or joysticks
