It has been over 5 years now since I had a Sun 4/280. I gave that away to someone else on the list. That system had an Xylogics 7053 SMD controller with a couple of Hitachi 900MB DK815-10 SMD-E ~8-inch drives. I forget the details now. >From a quick look online the Xylogics 7053 SMD controller has a CMD port, and a DATA 0,1 and a DATA 2,3 port. If I remember right the CMD port was cabled to the CMD in port of the first drive, then the CMD out port of the first drive was cabled to the CMD in port of the second drive, then the CMD out port of the second drive was terminated. The DATA 0,1 port must have had a Y-cable that was split to the DATA ports of each drive. There were other Xylogics SMD controllers as well. Which controller do you have in your system?
