	I believe that the +5v on the B port has in fact been removed in the
'040 revision of the NeXT motherboard. It was sometimes useful, but after
all, the +5v isn't a standard part of the RS422 specs. The docs I have read
on the '040 board show two identical ports which conform to the "standard"
set on the Macintosh.

	Standard Macintosh MIDI interfaces should still work, but devices
which required that +5v will need to find power elsewhere.
