| 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.
