but on Fairlight CMI IIx QFC9 board you don't find WD1771 floppy disk controller but one FD1791... Picture of my CMI IIx in sounds voices testing :
I have repair for many time my fairlight... and working for modify the QFC9 (Floppy Drive board) but I am in way with no simple solution at this day...
More information on CMI IIx service manual here (all board's specially QFC9) : http://egrefin.free.fr/images/Fairlight/CMI2x/CMI2xServiceManual.pdf
The Fairlight File System are QDOS it's same of MDOS (Motorola DOS) fairlight change M in Q (Qasar M8 first name of prototype beford Fairlight C.M.I. released). Yes Fairlight Qasar M8 are a simple based evolution of Exorciser from Motorola !
when Motorola making the Exorciser, it's one of first complete developpment system for 6900 and 6809 CPU... And this system have floppy drive (8" and after 5.25"), and the Disk Operating system are MDOS !
Your found more information about MDOS here (totaly compatible with Fairlight QDOS) : http://exorciser.net/excorciser_en.htm
I tested AnaDisk for make some disk image from original Synclavier and Fairlight 5.25" en 8" floppy disk, but It's not a great succes...
I have some good images from Synclavier I but not for Synclavier II (bad images) and for Fairlight... I not sucess to connect Qume Floppy Drive to PC floppy interface controller (not soft but hard).
Yes Fairlight have too type of format single side (6800 sound disk and system disk for CMI I and II) or double side (6809 system disk for CMI IIx).
I am ready, if you want help and beta tester for all tests !
I have these synthetizers and they are available to make experiments !
I think it's good help for the HxC system work on the Fairlight and Synclavier,and may be for Emulator II or III in the future !
