  Thanks for the replies so far: I have condensed my responses thus:

  Ah, yes. For once, I have tried to do all the obvious (to me)
things before asking for help... it was late last night when I
posted... I neglected to add:

 The drive is terminated with a valid RL02 terminator.. I have
checked and rechecked the cable, and run it reversed (on both ends)
just for grins, and I have verified that the 'door closed' switch
mechanism is in fact sensing top down and pack cover installed on
top of the pack.

   Cool! Cue Johnny Carson Imitation: "I didn't know that...."

  Other possibility is that the cable is open somewhere...

  And I would like to *personally* thank each and every individual who
specified key-less ambiguous connectors for thier design. Too bad
you can't be made to compensate for lost time/headaches/fireworks.

   Done that. All fine.

 
  I still think I'm at the point where I would like to speak with
someone who really knows these devices from having worked with/on
them... I can do just so much with installation manuals and printsets.

  Cheers
