I'm trying to get a Maxtor 8760S and/or a CDC 94191-766 (one at a time) working with a 3/50. I've been trying for quite a while. What I've got is: SUN 3/50 DB50><DB50---CENTRONICS><CENTRONICS--8760S--><TERMINATOR When the computer is powered on, and once in the boot process, the drive select light comes on on the maxtor and/or cdc, but when booting, though it finds si0, sd0, sd1, sd2, and sd3, it fails to figure out what kinds of disks are on there, and in fact it fails to recognize them at all. format won't work; it says there are no disks present. What I want to know is: How does it figure out what kind of disk is attatched, and are there any programs for the Sun 3/50 which will let me probe the SCSI bus to diagnose my problem?
