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.
