INDEX
[1]Bus Adapter - connecting point for all SCSI devices
[2] Wide SCSI Device - accepts IDs from 0 to 15
[3] 68-50-Pin SCSI Cable - adapts from wide to narrow connectors
[4] Narrow SCSI Device - accepts IDs from 0 to 7
[5] Terminator - device on the ends of a SCSI bus to prevent reflected signals on the bus
Because some narrow devices have only 50-pin connectors, they do not transmit the eight extra bits of data needed for
the wide device on the end of the bus. Using only 50 lines also prevents the narrow device from passing along the IDs
of devices at ID 8 or above.
