This system requires full keyboard emulation to work correctly. At startup, full keyboard emulation mode is enabled by default. Whilst in full keyboard emulation mode, some key associated functionality may be disabled (like the ESC key for EXIT). The keyboard emulation mode is toggled using the "Scroll Lock" key (by default).

Known Issues

The emulation of this system is Preliminary.

In particular, disc emulation is not correct so it fails to boot!

History and Trivia

This system is an update to the Atmos.

The Oric Telestrat is the successor of the Oric 1 and Oric Atmos with which it is compatible. It was launched some months after Oric was bought by Eur├ęka, a French company in 1985.

It was designed especially for telecommunications, like the Goupil 2, the Thomson TO-9+ or the Exeltel. It was designed to be used with the Minitel (French videotext terminal): it has a special ROM (8 KB) enabling the Telestrat to act as a videotext server.

A 3" floppy disk drive was available (400 KB) which run under StradSED (the Oric operating system, compatible with the old Oric DOS).

Several ROM cartridges were developed for this machine: Midi software (unreleased), Hyper Basic (compiled basic), Telematic Basic (designed for telecommunications), etc...
