    The board is from Sun Remarketing and is labled as being manufactured by
them. It is in an Apple Lisa and converts the signals from the external
parallel port to those of the MFM drive. The converter and hard disk are
mounted directly above the floppy drive internally with a ribbon cable going
out the back of the case to the external port. I'll look at it again when I
get home and post specifics on it. Unfortunately, I don't have any
documentation on the hard disk setup.

    I've had a few of the Adaptec boards, including one mounted in an Atari
SH-204 hard disk, converting from the ST's interface to the MFM drive
mounted in the enclosure.
