Fairlight-CMI

Hi,

 I was wondering what the difference is between a Q-077 card and a Q-777
card ? Has anyone studied the schematics of both cards ? It seems that early
series 3 systems used a Q-777 with a SCSI - ST 506 controller card and a
ST-506 hard disk. This makes me think, is there much of a difference between
these two cards ? Could a Q-777 card be converted to a Q-077 card ? I would
appreciate any info on this.

Many thanks,

James Thomson

The cards a very different. You are correct that the Q077 is for ST506 
standard drives; and Q777 is for SCSI.

The cards have their own drivers in the EPROM on the card.

Don't get too excited about the Q777 SCSI card, it is SCSI1 standard 
and many SCSI drives do not work with it - Fairlightus caveat emptor.
