***Info:...
***Versions:...
***Features:
o   Allows the WD7XC10 based designs to work with a generic "Super l/O" 
    device or with the WD76C20 and WD76C30
o   Replaces majority of external "glue" logic, up to 13 devices:
    - AT bus address buffers with 24 mA drive
    - AT bus interrupt multiplexing, and interrupt pull ups.
    - AT bus DRQ multiplexing and internal pull downs.
    - Keyboard/mouse interrupt latching and clearing functions
    - A20 Gate logic
    - Controlling the IDE data bit 7 at address 3F7H.
o   Allows implementation of a desktop system with only three external 
    devices
o   Direct connect to AT address bus SA1 through SA19 and LA17 through 
    LA23 with 24 mA drive
o   DAC multiplexing and RESET generation
o   DRAM WE signal from WD76C10 inversion and buffering
o   SMEMR and SMEMW generation with 24mA direct drive
o   Divide by 2 or divide by 4 clock output
o   136-pin MQFP package
