SCSI-Floppy Card

A few days ago, I was in a local used electronics/Junque (only high-class stuff here :-)) and found a rackmount case with PS, SCSI cables, and three devices for five bucks. Took it home, blew the dust out, and found I'd gotten a Exabyte 8mm tape that worked perfectly with my VAXCluster (once I'd reseated the cards, blew the dust out and ran a cleaning tape through it), an Archive 160 meg QIC drive (have no use for this, anyone want it?) and a 5.25 in floppy with what claims to be an NCR SCSI intereface bolted to it. It's this last I need info on. This interface board is the same size as the drive; at one end is the power plug (it appears to be powered independently of the floppy) and the SCSI header. The other end has a 34 pin header with a standard cable going back to the 34-pin edge connector on the floppy. Has an NCR 5380 and an Intel 85272 as the main chips, with a lot of glue, as well as a 80188 CPU with ROM. There are two switch pack, one 4-pos, one 8-pos. The 4-pos pack has the first three positions labeled FT and the last position is labeled EXT PF. The 8-position pack has the last three switches labeled ID (almost certainly the SCSI address). Anyway, anyone ever seen one of these before? I'm a little scared to just plug it in; I've seen lots of tape drives but this is the only SCSI floppy I've ever seen, and I want to take good care of it :-). Any info greatly appreciated. Thanks in advance! Dann Lunsford
