I'm still not clear for some reason.. So I can put *any* SCSI drive that has
an SCA connector into a Sparc 5 and 20? And likewise for any SCSI drive that
has a 68 pin connector into an Ultra 1? What about LVD, etc? I would really
like to put a pair of modern Quantum Atlas 18GBs drives into my SS20
(disregarding heat issues) Can I do this?
