don and greg – my scsi drives have keyed sockets, but cable makers rarely
use real keyed connectors (too cheap i guess). recent experience with
following the red stripe on a floppy drive caused my friend to get it wrong
(mfr didn't do things right and failed to provide keyed connectors). wish
it weren't so, but you're right. pin1 marking is one guide, key matching
another, and 50/50 permanent drive light the worst. the red stripe should
usually be right, but may not always be. best to really look at what you're
doing. the resistor packs are easy to overlook. i know of no controller
maker who gives you diagrams of the a0,a1,a2 device select pinson various
drives, either (enormously helpful info as some drives have the Ax pins
mixed in with a bank of other jumper selection options in a big block which
is not marked at all!). quantum sends their drives out configured as #6 or
#7, weird! too bad all scsi drives are not accompanied by at least minimal
documentation.
