TOPIC




    I have a Macintosh Plus, with an external SCSI hard drive that has worked
    reliably for over a year. Suddenly the Macintosh won't recognize the
    drive, though both the Macintosh Plus and hard drive work fine separately
    (for example, using the hard drive with a Macintosh SE).

DISCUSSION


    Most probably something has blown the IC on the hard drive's analog board
    that controls the SCSI reset line. Since the Macintosh Plus (and the
    Macintosh Portable) doesn't have SCSI termination power, this problem can
    only be fixed by replacing the hard drive assembly.
