* See fccpu30.cpp
*
* Misc links about Force Computers and this board:
*-------------------------------------------------
* http://bitsavers.org/pdf/forceComputers/
*
* Description, from datasheets etc
* --------------------------------
* - Desktop station for 32 bit VMEbus environments
* - Two 9 slot motherboards for A32/D32 wide VMEbus (Pl,P2)
* - 280W power supply to drive VMEbus and mass storage memory
* - 7HE 19 inch metal chassis including modules for drives,
* power supply and connectors (344mm x 520mm x 400mm).
* - High modularity(!)
* - One 1HE fan module including 3 fans for optimal cooling
* - Flexible mounting and very little time expenditure for
* repairs through modularity
* - Status indicators and switches of the VME boards are
* directly accessible on the front of the system
* - One 5 1/4" full height space for the floppy drive
* - One 5 1/4" full height space for the winchester drive
* - Up to 6 free slots for system expansion
