Fairlight-CMI

I think that I can confirm that the Fairlight OS (QDOS) is based on
Motorola's MDOS. The keywords are EXORciser and also EXORdisk. The
EXORciser was a proto-pc system that provided a "surrogate prototype
with which to edit, assemble, and modify programs in real time on the
actual hardware", according to my 'Motorola M6800 Programming Reference
Manual' M68PRM(D), dated Nov 1976, and printed in 3-84. Still in perfect
condition...

Of course, many mods were made, in order to support the dual-CPU nature
of the QASAR/Fairlight, as well as the sound hardware. Custom routines
are in ROM firmware, which could be updated (although mine never was).

The QASAR/Fairlight had/has word processor software (since, at the time,
that was one way to sell boxes and keep the music end going), as well as
various development languages (assembly and BASIC). I strongly suspect
that the IIx (based on 6809) and firmware changes would mean that there
would be different versions of software. Not 'one size fits all'.
