The Thomson TO 9 plus is the successor of the Thomson TO 9 which had a very short career. Its characteristics are the same than the Thomson TO 8/TO 8 D. In fact, it was fully compatible with it and by the way with the Thomson MO 6. It was, like the Oric Telestrat designed to be used as a Minitel (french videotext terminal) server and has a built-in V23 modem (1200/75 bauds) which was accessible under Basic. It was sold with a communication software, a word processing (Paragraphe), a data base (Fiches & Dossiers) and a spreadsheet (Multiplan). Contrary to the TO 9, these softwares were'nt on ROM. As the other models of its family, despite the 8 bits processor, almost all the memory (485 KB) was available thanks to a transparent 16 KB bank switching mechanism.
