Multiple Architecture Adapter Card

      This board design method decreases the cost of supporting
multiple computer architectures when designing an adapter card.

      The design method is to put connectors for different computer
architectures (for example ISA and microchannel) on different sides
of the card.  Logic common to both architectures is permanently
soldered to the cards.  This would include all of the logic for the
major function of the card as well as some logic common to all
computer interfaces.  The logic unique to each computer interface
would be socketed.

      This approach allows the physical board design costs to be
shared for the multiple architectures while optimising the logic
associated with the individual computer architectures.  With the
availability of high function PALs and FPGAs the number of socketed
interface chips can be minimized.
