They are for reading DOS format 5.25" floppies on a Mac. Dayna made several variants for reading 360K and 1200K disks. I think that you'l need a system extension as well as the hardware itself.The drives should work on virtually any SCSI capable Mac, but they are incompatible with recent system software. Dayna don't have a great record of supporting older hardware, alas. However these things do pop up rather a lot and the power supply pin outs have been posted on the comp.sys.mac.* news groups in the last year or so, so check out DejaNews.
