|  |     This is probably not the right note, but best I can find.
    Our school was recently given a CD Drive and told it was for
    a Mac.  But the connectors are not 'normal' SCSI.  The are
    normal 50 pin connectors (two rows of pins), like the
    connectors on a SCSI Hard Drive...like the 'internal' SCSI
    but not the connectors normally on an external box.
    I think this CD came from a PC.  Did they use a different cable?
    Another difference....there was a dip switch with what looked like
    a 'terminator' switch and SCSI address (and maybe one more switch?).
    But the SCSI address switches were 4 bits, not 3.  Does this make
    sense?
    thanks

    Are you sure it's SCSI? Seems to me most of the CD ROMs for PC's are
    IDE or EIDE. I guess it's possible that the drive is using a ribbon
    cable to connect externally, but I've never seen one do that before.
    Are there any markings on the drive that could help identify it?
    
    I used a PC CD ROM on my Mac for a long time. It was SCSI and it used
    the same 50 pin connector the Mac uses. I used FWB CD ROM Toolkit to
    drive it. I would imagine that any SCSI CD should meet the standards.

|  |     With regard to "the same 50 pin connector the Mac uses," that's not a
    Mac standard - it's a SCSI standard.  There are only two different
    connectors used by standard SCSI devices:
    
    o   The 50-pin AMP connector we're used to seeing, often called a
        "Centronics" connector, after the early 1970s dot-matrix printer
        that popularized it and still used today on parallel printers
    
    o   A metal connector, much more compact, that looks sort of like a
        squished D-submin connector with 68 pins - this is for SCSI-II
        (fast & wide)
    
    PowerBooks use that little HDI-30 connector, and a very occasional
    device (Zip Drive comes to mind) uses a 25-pin D-submin just like the
    one on the back of a Mac system.  My Apple scanner has one 50-pin
    Centronics connector and one D-submin.  I've never seen a SCSI device
    that used a ribbon connector externally, and I'd say it's highly
    unlikely - especially with FCC requirements about shielding.
