History and Trivia

Despite its name, the TO9+ is much more based on TO8 technology than TO9 (same video and memory systems, same floppy controller, same mouse, similar startup menu). However, as the TO9, it is intended as a semi-professional product. It keeps the desktop look of the TO9, with the separate keyboard. It now has 512 KB of RAM (inextensible), the BASIC 512, and an integrated 3"1/2 floppy drive (double-sided, unlike the TO9 one). Also, software formerly provided in the TO9 ROM are now supplied on floppies. Finally, it has enhanced communication capabilities by integrating either a MODEM or a RS232 extension (not emulated, alas).
