A few weeks ago someone (Sorry, I forgot who) pointed out a DSSI tape unit available on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5144248734 I bid on it, thinking that it would be phun to play with at a low price. I won, and the unit contains a couple of old DDS SCSI tapes but more importantly a CMD CDI-4000 SCSI/DSSI converter which appears from the SET HOST/DUP firmware to be identical to my other CDI-4000 which does either SCSI disks or tapes just fine. Woo hoo! Score. Thanks Paul
