International ClassesH01R 023/68H05K 001/11 AbstractA reconfigurable apparatus for computing systems including a set of baseboards and a family of daughtercards, together with a programmable interface to an external bus for a host system. Daughtercards attach to the baseboard through complementary connectors mounted on the baseboard and the daughtercards. In addition, daughtercards are constructed to allow stacking of daughtercards vertically. The baseboard and daughtercard approach of the present invention allows simple, incremental upgrade of installed boards by adding or replacing the daughtercards and allows simple migration to new systems by changing baseboards.Other References
