It's great that the zip works on your 4400. quinterro beat me to the punch. You can use Apple System Profiler, SCSI Probe or similar to reveal the SCSI addresses that the system detects with the slider switch in SCSIID positions 5 and 6, and make sure they really are 5 and 6 respectively. Then SCSI Probe your Quadra 700 system to get the complete SCSI address space assignments without the zip installed to make sure there are no conflicts. You can also see if the Quadra 700 SCSI bus has too many or too few terminators hanging off the starting and ending bus ends. The usual rule is one internally at/near the internal end (usually the internal HD) and one at the far external cable end if there is an external cable. Enabling the internal zip drive terminator if it is last on the cable is fine, no need to plug an old fashion terminator pod on the output connector. It is safest if the zip cable is an official Iomega labelled one hooked per the instruction diagram on the bottom of the drive, not a RS-232 straight thru patch substitute. If you have a CD/DVD burner driver/software pkg configured, you could try disabling the extension to see if there is some identity crisis going on at initialization time...
