- SCSI-II adds additional commands, Fast SCSI, and Wide SCSI.
-
- Fast SCSI will do 10M words / sec synchronous, compared to
- SCSI-I's maximum of 5M / sec, or ~2.5M/sec asynchronous. Wide
- SCSI comes in 16 and 32 bit widths, which combined with
- fast SCSI can give you 40M/sec (For best results, use
- differential SCSI in combination with fast SCSI).

- Microsoft is responsible for propogating the evils it calls DOS and Windows,
- IBM for AIX (appropriately called Aches by those having to administer it), but
- marketing's sins don't come close to those of legal departments.
- Boycott AT&T for their absurd anti-BSDI lawsuit.
