Two of these SCSI buses were used to store video data, and the third to store audio.
The Jamaica had two drive bays, each with its own SCSI bus.
Every device attaches to the SCSI bus in a similar manner.
Each device on the SCSI bus has a signal transceiver.
Transferring data on the SCSI bus is managed by the host adapter.
Most parallel SCSI buses are terminated at each end.
So in the case of a differential SCSI bus, it is possible to terminate all 18 spare signal wires with just one resistor.
The parallel SCSI bus goes through eight possible phases as a command is processed.
Parallel SCSI buses must always be terminated at both ends to ensure reliable operation.
Another requirement is that any parallel SCSI bus must be terminated at both ends with the correct type of terminator.
