Good point, I just looked in the back of my CD-R box and the terminator switch runs to a jumper on the drive itself, so I guess that kills the 5v+ and not ground, didn't think about the resistors floating, guess that would cause errors! :bow:
So, the question is can this board be bypassed? And if so how would we connect the active terminators? One on the end of each 50pin connector? Or both to the external?
With both active terminators being connected to the external connecter of this pcb I would think that the internal connecter is wired in next to the controller and the terminators on either end of the chain? So both internal and external devices can be connected to the external connector like this:
internal and external devices being used:
(active term)======(external device)======(SCSI Controller)===(internal device)===(active term)
or
(active term)======(SCSI Controller)===(internal device)===(active term)
for only one device being used?
"===" is of course the 50pin ribbon cable..
