I know people keep asking this with alarming regularity, but does
anyone know the correct way to terminate the SCSI chain in a IIfx:

	1. With only an internal drive.
	2. With both an internal drive and an external tape drive.

Apple is woefully negligent in this area; although the IIfx comes with
"Technical Info" and "Setting up Your IIfx" manuals, neither of them
address the question.  They do, however, enclose a single slip of
paper that helpfully states "The SCSI chain should always be properly
terminated," or something equally inane.

Basically, I know I'm supposed to use the special black-plastic
external terminator if I have any external SCSI devices.  But I've
also heard that the gray-plastic T-shaped doohicky that looks like an
extender is, in fact, an internal terminator and should be used -- at
least in some cases.

Please either post or respond by email; I'll summarize to this group
once I finally get this all straightened out.  And if you do reply,
you can faithfully assume that I know absolutely nothing about any of
this -- don't worry about explaining things at a very basic level.

Thanks in advance for your help.
