    Teo is an emulator of the Thomson TO8 microcomputer

    Teo is an emulator of the Thomson TO8 microcomputer for PC, running on MSDOS, Windows and Linux. The compatibility is close to 100% for softwares which don't use non emulated peripherals and don't hold physical protections. In other words, if a software doesn't work on Teo, so probably : 1. it needs the presence of another peripheral than mouse, light-pen, joystick, tape recorder and disks (so it won't run as long as this peripheral is not emulated), 2. its physical...
