I just ordered a Adaptec ACB-4000 disk controler to run a ST-506 Maxtor for a Sun 3/60, but I keep hearing about a ACB-4000A. The question is: Do I need the *A* version for what I am doing and secondly what EXACTLY is the difference between the two. Greg Ansley gja@vta.atl.ga.us ...!gatech!vta!gja

Originally, Adaptec had two different 4000 type cards, the ACB-4000
was for soft sectored disks and the ACB-4010 was for hard sectored disks.
When they went to the ACB-4000A, they simply implemented both options on
the same card. they also did some firmware changes that allowed for a little
more compatibility with the full SCSI Common Command Set.
