Apple SCSI really is just single initiator SCSI.  I've had no problems
getting such "normal" SCSI drives from MaxTor, CDC, etc. to work on a
Mac (it's a bigger pain for a Sun 3/60 though!)

What your problem might be is a lack of real driver software for the device.
Drives DO differ, manufacturers DO make mistakes.

One of the major reasons for custom ROMs is to implement special commands
that the installation software can use to detect if it's formatting a drive
it is supposed to.  (e.g. Rodime's Driver only works on a 1400RX and Jasmine
driveware only works on a Direct Drive 140, but both drives are the same
Rodime RO-5000s mechanism!)
