As I was just reading on Lowendmacs.com the internal SCSI connector on the

the 7300 is for the external SCSI and that is 5mb transfer rate.

Bus 0 is internal only, and is 10 MB/sec.

Bus 1 is internal AND external, and is 5 MB/sec.

The reason for including a 5 MB/sec internal bus apparently was 
incompatibilities with certain internal peripherals in early PCI Macs (Zip ?).

The separate buses were deleted on the Beige machines, and the Beige machines 
were provided with a single internal AND external 5 MB/sec bus, Bus 0.
