"Fast" is a prerequisite for any new disk; "wide" means the controller has the extra bits required to talk to a "wide" SCSI device, should you wish to connect one. > And, finally...is there anyone out there from the Toronto > area that would know where I can find said controller?

If you want to look at one to verify this for yourself, the little resistor packs should have '111' on them, but _not_ "221331" or "220/330" or similar. If there aren't any resistor packs, then you either have no termination, or you have active (and possibly automatic) termination. > Marc G.
