A new OS running on a mass storage (64 GB) on the Oric

Demo on the real hardware

Orix running on atmos

Twilighte card

sittler card

Expansion board

this card can connect the atmos to twilighte card without electric ribbon.

Some demos

Boring to trying to find storage on the oric? like Floppy disk controllers (microdisc/jasmin) ? Orix and this hardware can correct this. Because you can have a 32 GB usb key and a 32 GB on usbcard at the same time on the oric to start everything you want from this storage.

Speed to load a file : at least 46 KB per second.

Orix runs in a ROM.

Some apps are already working.

The goal is to provide everything with one hardware and one OS.

Orix : what is this ?

Bank 7

telemon 3.0 contains some primitives :

  • all primitives from telemon2.4 without minitel routine (keyboard, joystick management, print, hires primitives charset and so on…)
  • XOPEN : open file from sdcard
  • XFREAD : read file from sdcard

Telemon uses OVERLAY RAM for :

  • Keyboard buffer
  • RS232 buffer.

Bank 6

bank 6; basic 1.1 modified :

  • Telemon does a test signature on the rom, when it found some bits, it starts the rom, if basic 1.1 is not modified, telemon will start this bank).
  • without ram checking (to start quicker)
  • 'cload' command is removed (code replaced by nops)


* in bank 5 : Orix is a 16 KB bank which handles interpretor, some primitives, contains all code to manage starting apps, reading file, some tools * Orix does not use OVERLAY RAM, but Telemon (since 2.4 does)


Orix has be done to have an universal OS (working on all Oric machine). The main goal was to start and code on the native machine.

This project is a the result of 8 months of work and 8/10 hours a week (building electronic card/OS/emulator, compiler …).

If you want to know the story of this project, you can read the readme of the orix github source code. Orix story

The first preview of Orix was at the Alchimie meeting in France (october 2016).

The first released version had been shown at the ceo meeting (january 2017)

The final card was release in June 2017.
