     The generic Quantum Q280 is the same as Apple's 80SC, except for the
on-board EPROM. A Q280 I purchased formatted fine using Apple's HD Setup,
but wouldn't work properly with the System software. When I swapped the
EPROM from my Apple 80SC into the generic drive, it worked fine. Both drives
had EPROMS with Quantum part numbers on them. When I called Quantum to order
another EPROM, I was told the EPROM from the Apple drive with the Quantum
part number was proprietary. Very tricky indeed!
     Note that there are third party formatting programs that will work
correctly with generic Q280 drives.
