I found this in one of my cupboards, don't know where or when I got it. Micro-systems development Inc. Dallas Texas Model SD-2 Two TEC 51/4 floppy drives, Model FB501, mounted vertically Built in AC supply Rear panel has two 6 contact female DIN sockets and one 24 contact female connection similar to a Centronics printer, only smaller. The construction is generally similar to that used on Apple ][ drive cases, although I suspect this might have something to do with a PET. Can any one enlighten me? Regards Charlie Fox Charles E.
