The SCSI2 socket is, I believe, an Eesox one. No software to 'drive' it. It
ran our SCSI scanner for many years (and still does) before we bought the
CD-writer, so it must be correctly 'set'. It also had no problems with an
external SCSI hard drive that has long since passed over the Rainbow Bridge.
