I guess this is the right place to put this... forgive me if it isn't, but nothing else seemed to fit.
I've been looking around for some SCSI drives for some of my old Macs that need them, and I came across a listing for "SCSI jumpers". The listing says they're "Used for SCSI, SCA, Laptop, and FC drives (Not used for IDE drives)". They're described as being 2.00mm in size. Further research on my part tells me that the ones used on CD/DVD drives and IDE/ATA hard drives are 2.54mm.
Not having dealt with SCSI drives before, this was news to me. Through my travels, I gathered an assortment of drive jumpers from various dead drives that were being discarded. (Can you really ever have too many spare jumpers?) Some were taken from some old PC floppy drives, and were visibly smaller than the standard ones I'd seen. Since they were free, I figured that they may come in handy if I ever needed a smaller jumper for something.
Since I got the old Macs without any SCSI hard drives in them, I can't do a direct comparison. I'd hate to buy a SCSI drive to find out it didn't come with jumpers, and that the ones I have won't work. Do SCSI hard drives really use different jumpers? Does that also apply to all internal SCSI devices (like SCSI CD/floppy drives)? Could those smaller floppy jumpers I've accumulated be the same ones used on SCSI drives, or are they something completely different?
