Do I need to terminate a 50-pin ultra scsi drive if it is the only drive on the cable and there's only room for one device? Eg. there's only two interfaces, one for the the drive and one for the card.
Usually, SCSI devices come with the termination built into the device. Older devices actually had two or three terminating resistor packs plugged into the card or drive circuit board. More modern ones have DIP switches to turn the termination on or off.
Essentially, on a SCSI daisy chain ribbon cable with multiple connectors, only the first and last physical device needs to be terminated. Usually SCSI devices come from the factory already terminated. If you have only one device to connect check and see if there is a DIP switch to change. I would go ahead and connect it. If it works, it's probably already set properly.
That said, I have worked with daisy chains of SCSI devices where a particular device would only work if it were terminated even if it was in the middle of the chain. s

I solved my own problem. The card said "insufficient termination"
