hello,
  Look in Amazing computing from quite a few months ago.  Then show the
pin-outs for the 25pin and 50 pin SCSI connectors.  It seems that half
of the 50 pin cable is for grounds.  That's how Apple got it down to 25
pins.  They use the sheild as a return ground for the signals.  I think
that some of the other pins might be ground to, (I haven't looked at
the pin-outs in some time).

To the guy with the stardrive, how well does it work with the seagate drive?
(transfer rate, utilities?)  I was considering that for my starboard or 
getting a Comspec auto-booting SCSI controller. (I have a LUCAS and know
that the Comspec will work with it.)
