uVAX II + KFQSA + DSSI Drive and the last touch?

O.K. thanks to Jochen and Chuck and from some Google search I
learned that:

- terminator isn't absolutely necesary
- I can hook up the round cable directly to one drive
- don't need the front panel with the unit id if I set
   the KFQSA to be unit 0 only

I could actually squeeze the round cable under the qbus backplane
where the RQDX3 cable runs through. So, it looks pretty neat now.
The Qbus is a full house (aren't the board touching each other
possibly causing all kinds of shorts?)

Anyway, my biggest problem was the power hookup which is
different on the RF72 from the normal ones that any SCSI,
IDE, MFM, TK70, etc. drives have. Luckily I could find a
connector in my nick-nack box but I don't know if I have
connected it properly, it doesn't work right. Here is how
I connected:


                                   rd bl bl or/yl
                                    | | | |
                                 | | | | |
                                 | | | | |
  ||||||||||||DSSI||||||||||||| wt rd bl bl or

I removed that connector from a little adapder board on a
mounting bracket that I got with one of the drives. The
traced on that board told me that the orange cable isn't
connected at all and the white cable is hooked in the
middle of the series of pins that make the DSSI connector.
So I concluded that the white cable would better not be
connected to the power feed and left it open. But somehow
this isn't right.

What happens now when I power up is that the drive will
emit no sounds at all, like spinning or attempting to spin
or seeking or anything. When I do connect my one and only
front-panel I see all three LEDs lit: error, run, and
read-only. And no change when I push any of those buttons.
So, I suspect that my power hookup is wrong, could you
tell me how this power thing should be connected?

Thanks,
-Gunther
