That'd be a kind of interesting way of doing things because you could
get around the "slow slot i/o" problem by running the second "slot"
in front of the older slot at the full speed of the machine and just
tell designers to design cards that will work right at the full speed of the 
machine.  I had thought that another good idea for getting around the slot
i/o problem would be to have an ID word which would make force the card
into "FAST" slot mode; however, I think that your idea is probably better
for making a practical solution.  You could have the new "slot" for accessing
the fast side of the system.. hmmm.. you really wouldn't even need to run
some lines to that slot because they'd be duplicates of the first (like
you could suck power from the first part like cards like the twgs do now).

Hmmm... now, if they would only move the 8530 serial i/o locations out
of the i/o locations, we'd be in business.. :-)
