Subject: Ultra 30 floppy disk drive issue

    Greetings folks,

    I have been playing with my SPARC and managed to get half way through my
    over clocking endeavor (mystery jumpers on the board are slowing me down)
    and wanted to attach a standard floppy drive in order to get basic file
    transfer (for firmware, etc).

    The floppy drive header is on the very top of the motherboard. I have
    attached the ribbon and to my horror, upon turning on the system watched as
    pin 3 on the ribbon melted the sheathing on the ribbon from motherboard
    connector to floppy drive interface, all in a matter of seconds. I replaced
    the drive (after making sure the system had not died) and had the same
    result. Two floppy drives and three ribbons later, I can only assume the
    floppy drive header is either not functioning normally or my guess that a
    standard floppy drive could be used was wrong and the pin outs are
    different.

    Any insights will be much appreciated.
