Can you provide specific details of what you had to do to the sequencer
code for the aic7xxx, the NCR does infact use sequencer code and the
same fix could probably be adapted into it makeing the Grand Prix supportable.

It may also fix the problems with certain CDROM drives and TAPE drives
that show a very similiar failure to the Grand Prix drive.
