Technical Notes: Hardware
The SCSI Parallel Interface is an industry-standard parallel data bus that provides a fast, consistent method of connecting computers and peripheral devices. The SCSI Architecture Model-3 specification expands the term SCSI to define an architecture that treats devices that adhere to the SCSI Architecture Model specifications in a consistent manner, independent of the physical bus to which the device is attached. Developers can write software that communicates with or controls SCSI devices and SCSI Architecture Model devices. Mac OS X supports application-level access to all devices that declare peripheral device types other than $00, $05, $07, or $0E.
