Yeah. Though I'm not sure if I need to terminate if all the connectors on the ribbon are being used by a device. If I use a SCSI cable with 3 connectors; one going to the SCRAM 500, one to a HD and the last one to a CD-ROM, would that be a complete and correctly terminated set up?


The thing you have to remember is that in ALL CASES on the SCSI bus, both ends of the chain MUST be terminated.  

If there is only one connector on the SCRAM, it should have an on-board termination on it's end, so that will take care of one end.  

The other could be taken care of by setting a termination jumper on the SCSI CD-ROM drive unit.

The logical SCSI chain would thus look like:
------------

This would be a correct configuration as it would have termination on both ends of the chain.
