I've never actually seen one, so without looking up the manual, I'm not sure. There are a couple poeple on the list here that I think have them, to bad they've not commented.

I'm wonderind if the HSD10 needs to be cabled to it, or if it is not used. There is a third possibility, the shelf might be split into two segments, one acting as a DSSI device and one acting as Narrow SCSI

OK, you've got a Narrow 4.3GB disk, not wide. The BA356 shelf, which is what I'm sure you've got based on the 8-bit personality module, can use either Narrow or Wide devices. The BA350 doesn't use personality modules.

No. If you weren't on the other side of the pond, I'd offer you something for it, but I fear what just shipping on the everything would be, even if the powersupplies and disks were left out!

If you got the cabling sorted out, it would be an excellent 2nd disk and backup device for the 3100 (minus the DSSI converter). Actually if you pulled the DSSI converter it should work on one of your other systems such as your SGI Workstation.
