We are considering expanding our MicroVax II's by adding third party disks/controllers. We are considering a Q-bus SCSI interface with a 150-300 meg disk. I would like to mount the disk(s) in a separate cabinet with its own power supply (we have "small-box" MicroVaxes). I have a few questions, though. Would we be better off with a EDSI or SMD interface instead of SCSI? Do they offer the same ease of expansion (i.e. daisy-chaining)? Is one significantly faster then the other? Most of the controllers claim to emulate DEC's MSCP. How close are they to the "real thing"? Does MSCP emulation mean you can boot off that disk? It just seems to easy, and the prices are suspiciously low (compared to DEC). Are we missing some important point? Have any of you done this before? Your comments/experiences would be greatly appreciated. Thanks in advance, Jim Cronin
