The SCSI Bus and This Jukebox
This jukebox is a “fast and narrow” SCSI device with the capability to connect to
either a narrow single-ended bus or a wide differential bus.
In the diagram below, note that the single-ended (50-line) bus is brought directly
onto the jukebox internal narrow bus. The differential interface accepts a wide bus
in its 68-pin connector, but only
uses the 50 data and control lines
that comprise the
"
narrow
" portion of the bus. The other 18 lines that provide the upper IDs and data
of the wide bus are ignored. Note that all lines of the wide bus pass through the two
68-pin differential connectors. The wide bus is maintained as a wide bus.
The
single-ended
connectors are 50-pin and can accept only a narrow bus. The
differential
ports use 68-pin connectors and can accept (and pass through) a wide
bus.
