 I'm in no hurry. Thanks for the offer, but you just finished
supplying me with all that documentation on the C4P. Someone
just down the street from me says he has documentation and
schematics for the mother board. I'll check that out first.
He also pointed me to a couple of great Compukit 101 pages:

 Looking closer, there are sockets on the mother board for 8 pairs
of 2114s. There is one pair of 2114s in the first pair of sockets
and one pair of 2114s in the last pair of sockets. It looks like
the select lines for the 6 pairs of sockets inbetween are wired
to these 2716s. So it has the feel of some kind if firmware
application.

 If she didn't understand, then the drives never would have made it
to the kitchen. I'm sure she just wants to make sure she doesn't
stumble into the kitchen one morning and stick a Pop-Tart into
one of your drives.
 In your house there is a path through the garage, a path through
the living room, a path through the dining room, and one bedroom
that I can just look into. My wife just wants a corner in the
dining room to set-up a trendmill.
