Usage notes

System ROM

There are ROMs for both 800 and 800XL models. By default 800XL(atarixl.rom) is loaded. Remove it or rename if you wish to use 800(atariosb.rom) ROM by default.

800XL ROM supplied in 2 versions:

  • ATARIXL.ROM - includes SIO turbo patch (fast disk loading). Loaded by default.
  • ATARIXLn.ROM - original 800XL ROM.

You can use menu to choose required ROM, or rename ATARIXLn.ROM to ATARIXL.ROM if you don't want to use turbo loading.

Turbo ROM has hot keys to control the turbo mode:

  • SHIFT+CONTROL+N Disable highspeed SIO (normal speed)
  • SHIFT+CONTROL+H Enable highspeed SIO

Additionally, you can control the speed of turbo loading in OSD menu.
