Zilog has a databook for telcom chips which has both chips inside.  I got
the data book a couple of months ago.

I am in the process of building a SCSI controller for my Commodore Amiga.  I
happens to be using a NCR 5380.  I got the part off Active Components, a
mail ordering place for about $13 Canadian a piece.  You can get the data sheets
for the Z5380 from Zilog.  According to Zilog's data sheet, it is identical to
the generic 5380 part.  You might want to get hold of the SCSI specs some
how as the data sheets do not explain about SCSI too much.  I got my SCSI
spec from Seagate for free.  Email me if you want the address of Seagate and
literature# to order.  I am at work (supposed to be anyway) and I don't have
them handy.  If you need more info/help, please let me know.
