Strange drive unit

That is an MSD SD-2 dual drive. It was sold as a premium drive for the Commodore 64, and supports either serial or IEEE-488 interfaces. It would work with a PET, as well, via the IEEE-488 interface. One of its compelling features is its ability to copy a diskette completely in its firmware with one command, and quickly. If you would like to sell it, I would be interested :>.

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.
