I found this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130693272424 and thinking of picking up a few, will they work in older Macs (with adaptors) for 6100/7100/8100 and also a 9600?
No, just no. Ultra160 drives are usually back compatible; many Ultra320 drives are not. You need to check the manufacturer's data sheet for that drive and confirm that it can be set to a backwards compatible mode, SE or Single Ended, IIRC. And you need the right adapter.Yes. SCSI drives are normally designed to be backwards compatible with all the older standards. I have never encountered one that wouldn't work with an adapter.
Did you find the drive manufacturer's support page? You quite likely need to set jumpers on the drive, as well as/instead of the adapter. The drive needs to be set in Single Ended mode - if it can.maybe it needs adjustments to the jumpers
More likely to work - but it's not the pin count that matters, it's the SCSI mode/s the drive is compatible with.68pin and NOT 80
