If You look into the May/June 1986 issues of BYTE (that was the time
BYTE was still readable), You'll find in Steve Ciarcia's column
a two-part article on
	"Adding SCSI to the SB180 Computer"
This gives You
a) a fairly good introducation into SCSI
b) a hardware description of the SCSI controller on the SB180/SB180FX.
The design uses the NCR 53C80 which uses a chip count of 1 (one)
plus a couple of terminating resistors, though it calls on the HD64180's
on-chip-DMA.

(I must admit, I own an SB180FX with the SCSI I/F but have not been
able to get it running yet 8-( )
