On May 9, 1988, AT&T announced the third release of SCSI peripherals for the AT&T 3B2 computer family. Included in the announcement were: Differential Host Adapter - Provides a differential SCSI interface for 3B2/500, 3B2/600, and 3B2/700 Computers. DM/300S - A package containing 1 300 MB (formatted) disk with a built-in single-ended SCSI interface. DM/300DS - A package containing 1 300 MB (formatted) disk with a built-in differential SCSI interface. 9-Track - A package containing a 1600/6250 bpi, 125 ips 9-track tape drive with a single-ended SCSI interface. 9-Track - A package containing a 1600/6250 bpi, 125 ips 9-track tape drive with a differential SCSI interface. The 9-track tape drive provides auto-loading of tapes and is packaged in a table-top package measuring approximately 9"H x 19"W x 24"D, with a weight of 85 lbs. In addition to the new hardware supported, software support for mirroring of disks drives was also announced. The mirroring software allows mirroring, on a partition basis, of any two partitions on any two SCSI disks. The software works on any 3B2 computer with the UNIX(R) Operating System V, Release 3.2. Also announced was support to allow multiple computers to share a common differential SCSI bus and share access to the peripherals on them. As with past announcements to this news group, in addition to announcing new products for the AT&T 3B2 family, we are interested in any experiences, good or bad, you may have with the AT&T 3B2 SCSI equipment. (Any comments on problems should include as much detail on system configuration as possible, including the UNIX(R) Operating System version.) We are interested in hearing of the applications you run in which you need the capabilities of SCSI, how well SCSI meets your needs, and if the performance and functionality were as expected. Also, what new features/peripherals would you like to see provided in future releases and how would they help you? We are also interested in comments on how knowledgeable the sales staff was, how long it took to get the equipment once it was ordered, and how easy it was to install. We cannot usurp the role of the support organizations to directly solve any problems. We may be able to respond to general questions on what was done, and perhaps why it was done, in our implementation. However, we can promise that all comments will be carefully considered as input to future releases of the SCSI products, and this will hopefully make upgrades to your system function better for you.
