There most certainly is a standard SCSI connector.  Many boring
pages of the ANSI SCSI standard are devoted to describing in
excruciating detail what standard SCSI connectors look like.

ps: the main problem that one is likely to encounter trying
to use a standard SCSI drive on the Mac is the various bugs
in the Mac plus ROM.  Here are some of the problems that
can cause serious trouble:

	1. ROM SCSI Manager can't read more than one block at
	a time safely.

	2. Blind transfers can't be used safely.

	3. Original plus ROM can't deal with drives that do
	UNIT ATTENTION on reset.

Problems 1 and 2 can be worked around in software ( simply don't do
blind or multiblock transfers until the SCSI Manager patches are
loaded ).  Problem 3 is more of a problem.  Either get the later
plus ROMs, or convince your drive not to do UNIT ATTENTION ( many
have such on option ).
