	After days and days of using FW+ in an attempt to get the
Phantom to appear, I finally did it.  Unfortunately, I didn't have my
logic probe with me right there, but I did manage to get it after the
machine had bombed (four bombs; don't remember whether that's bus error
or what).
	Anyhow, counting from the top end of the connector, the values
I got were:
			L
			H
			H
			P
			H
			(gap in connector)
			P
			H

"L" and "H" are Low and High.  P indicates a pulse.  Let me explain:
at first, there was no data on P (I think it was high).  Then I pressed
the spacebar, and I got a "make" pulse and a "break" pluse.  After
doing this twice more, the pulses all of a sudden didn't stop -- they just
kept on coming.
	I have no idea whether this is an accurate representation of what
was actually going on, because I think I might have had the probe set in
CMOS rather than TTL.  I'm connecting a buffer and a set of LED's for
further verification so I don't have to type with my ST's case off.
	Anyone out there have a logic analyzer they'd be willing to send
me for further testing???
