Doug -- thanks for the excellent explanation and a great diagram! Now it's all clear. Alas, I don't have a backplane or a place to stick one to, so I ordered a few recommended sca2lvd adapters -- the one Dan Jones referred to was reported "good" on comp.periphs.scsi is by Corpsys: http://www.corpsys.com/store/prodinfo.asp?number=SCA2LVD&variation=&aitem=24&mitem=82 and I also used to like excellent stuff from cablemakers.com, which is the best place I saw so far for all things SCSI if more expensive -- but those folks put up all the right photos, very professional. I also am going to get another adapter from scsisource.com, all different from the high-bit-squashing Taiwanese piece of art "v1.1" others resell... I'll report my findings here! -- Cheers, Alexy Khrabrov :: www.setup.org :: Age Quod Agis
