OK, I know someone is working on scsi chipset.  I found a way to get
documentation.  (It's  a secret ;-)).

Try calling 408-980-0414.  I also have a form to fax.  Fax requests to
719-630-8537.  They'll mail the stuff for free.  You get pictures and stuff.
;-)


There is the following in SCSI Products:

53C80 Family
53C90 Family
53C90/90 A-B
53C94/95/96
53CF94/96

As far as I know, almost all cpus use c80s.  The fx uses a special version
that supports DMA.  Only AUX uses this feature.  Quadra's use the c90 family
or was is c96?  Apple has found bugs in the Quadra chipset. ;-(  This is noted
in Developer tech notes.

I hope this info helps.
