I bought this new at COMPUSA while I was working there in the late 90's. Never used it. I've been lugging it around since then thinking I would have a need for it, but my likelihood of owning SCSI devices in the future is very slim. I see YouTuber's now using them in a nostalgic way and I hope mine finds a good home. I've regressed to vacuum tube technology and won't miss it.The best description is found on the box pictures and a Google search can get further into the details.
