That's what I was referring to when I said "can/will be keyed so that it
cannot physically get into a PCMCIA slot"

Not sure how it could be different given the backward compatibility and that
have the same number of pins

I believe not, no - only PCcard is "dual" voltage

More logical to acquire a 100/110?
