SUNW,spif and SUNW,xbox

[Mouse <mouse%Rodents-Montreal.ORG@localhost>]

I've got a SUNW,spif and a SUNW,xbox.  I've also got two cables which I
think are mechanically compatible with each of those (the cables and
the cards are not at the same location yet).  I've got the spif
breakout box as well.  (I think I have an xbox expansion chassis
somewhere, but I'm not as sure of that as I'd like.)

Does anyone happen to know whether the cables are identical between the
two?  If not, and it's not obvious mechanically, how can I tell which
is which?  I saw the cables earlier today and I *think* they're
mechanically identical, but I didn't bring them to the location where
the cards are.  I'll be doing that soon; this mail is written for the
possibility that my impression that the cables are mechanically
identical is accurate.
