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
