Orix

Introduction

Orix is designed to work with ORICHD (telestrat) and Twilighte card (atmos). See : http://orix.oric.org

Some code is done by Fabrice Broche (60%) and Jede (40%). Anyway, all minitel and FDC routines had been removed

Assembler : ca65 CPU : 6502 & 65C02 (but 65C02 not tested)

How to use it ?

This kernel is a set of primitives to displays string, open/close/write files ...

You need at least "shell" bank to use this kernel

Build option

Root file on sdcard

Pass to ca65 command line : -DWITH_SDCARD_FOR_ROOT=1 or else it will reads en usb key

here is the list of available "compile option"

• CPU_65C02
• WITH_MULTITASKING
• WITH_ACIA
• WITH_DEBUG : In that case, somes primitives send their debug to printer with a help of kdebug ROM.
• WITH_TWILIGHTE_BOARD

How does it starts

• Kernel tries to start binary set in his rom label 'str_binary_to_start'
• it allocates a process struct (first malloc)
• and register it in processlist
