    The biggest difference between SCSI and SCSI-2 is speed. Basic SCSI-2 can accomplish double the transfer speed of SCSI due some timing differences between the two standards. SCSI's maximum transfer rate is 5MB/s while SCSI-2 can handle up to 10MB/s. Both SCSI and SCSI-2 use the 50-pin ribbon cable to connect internal devices. External connectors on the SCSI or SCSI-2 chain may vary depending on the manufacturer of the controller and the device being connected to it. While SCSI-2 devices and controllers are supposed to be backwards compatible with their SCSI counterparts, my personal experience suggests you would have better luck trying to get a SCSI device working with a SCSI-2 controller, than the other way around.
