SCSI-based card readers - "LUN" based?
Posted by: tmtomh on 2009-09-07 06:54:59 This is an interesting example of something that's been discussed here before, for dealing with the scarcity of old 50-pin SCSI drives: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220468088819 It's a 50-pin card reader that takes PCMCIA, MS, SC, SD, and CF. The only thing is that it's "lun based not target ID based" - in other words, each card slot is not addressed as a separate SCSI ID, but rather is accessed via logical unit number (lun). I gather lun's are used for RAIDs, and I assume for partitioned volumes as well. So does anyone know if 68k (and, conceivably other SCSI-based Macs) can work with this type of unit? From what I can find out about it, its luns are static - that is, each card slot is assigned a certain lun regardless of whether there's a card in it or in any other slot. Does anyone know if this system - where the device and not the formatting software on the Mac assigns the lun's - would work with a Mac?

If that works, then it would be worth moving on to try more than one.
