The CP150B should be the same thing...
Are there no dipswitches at all on this???

There used to be a Caliper CP150 drive at work which is why I had the dipswitch settings written down. The settings were off some newsgroup. The drive was thrown out a while back so I can't check it for you.

You should be able to make a vague guess as to if it's a SCSI connector or not by tracing the ground connections on the plug. Half the plug should be connected to ground. Is it a Centronics plug?
