Fairlight-CMI

Was it supported by both QDOS and OS9?

Yes, the TVT card (as we called it) was mapped into processor 1's address
space. With the jumpers in the default position the 1st screen was mapped in
at 0xD000 and the 2nd screen was mapped at 0xD800. It's been 15-20 years, so
those addresses may be wrong.

 

did you work on the Series IIL?

Did you mean the Series IIIL - (3L) - I can't recall a Series 2 with the "L"
modifier.

But yes, I worked on all version of the CMI and ultimately MFX (and the
start of CC-1) until late 2006

 

Specifically, could the CMI boot QDOS and the CMI software from the HD, and
what happened to the notion of the "LEFT" and "RIGHT" drives in that case?

As far as I remember,  with only one floppy in the system and a hard disk
controller, the operating system (QDOS or CMI DOS) would boot from the
floppy first, if a hard disk controller was present half way thru the boot
up it would swap over to the hard drive and boot the remainder of the OS
from the hard disk. There was not a way to boot directly from the hard disk.
Once the system had booted, the floppy drive was then assigned the "data"
drive or drive 1.

 

Then came along OS9, this was a totally different beast and new Q077 and
Q777 ROMS could boot to the hard disk directly.

Sounds familier, but I cant put a face to the name.

Hi Steve,

Thanks for the feedback on the Q050. Was it supported by both QDOS
and OS9?

By any chance, did you work on the Series IIL? From the Series II(x)
service manual, I would guess that it used the Q077 with a Western
Digital 1002 to interface with an MFM drive.

I'd like to know if some versions of released CMI software were aware
of that configuration. Specifically, could the CMI boot QDOS and the
CMI software from the HD, and what happened to the notion of the
"LEFT" and "RIGHT" drives in that case?

I have a IIx (kind of a strange one, it was Herbie Hancock's) and 2.5
Series III machines (1 working Rev6, 1 working Rev9, and 1 basket case
Rev6). All great machines!

Also, I think you know another friend of mine, Joe Sleator. He's
cobbling together a IIx now.

Best,
Joe
