The NCR chips are the absolutely best chips for implementing SCSI.
BUT, they are very difficult to program properly. SCRIPTS can be
a cobra biting you on the butt at worst and a god send at best.
With a properly written driver and SCRIPTS it's possible to attain
90% SCSI bus saturation.
For reference sake, I'm able to get 18.5MB/sec on a SparcStation 10
and the same performance on a 486 w/PCI running Solaris X86..
