The more things change, the more they remain the same!  Sounds like the
S-100 bus.  A nifty idea from the past.  Power supply and bus connectors
on the backplane -- any board that conforms to the protocol can be swapped
into the configuration.  What a disaster for the planned obsolescence
folks .... they wouldn't be able to sell us a whole new set of hardware
every n years.  Now, before I get flamed for suggesting such a tacky
thing as the S-100 bus, let me say that I realize that it had (has) some
serious disadvantages, but the **CONCEPT** was, and is, an excellent one.
It worked because of its simplicity and the fact that it was a hobbyist
bus, and did not get taken over by the hi-dollar market.  Face it, buses
like the VME, multi-bus, etc. could never fit this particular niche, not
because they are inappropriate, but because the cards for these buses are
priced beyond the reach of most of us -- for personal use.
