    If I am not mistaken you can cascade two 74LS193s to form 8-bit Up Counter.
    OR
    You can use these Philips ICs
    1) 74F269 8-Bit Bidirectional Binary Counter
    2) 74F579 8-Bit Bidirectional Binary Counter; 20-Pin (3-State)
    3) 74F779 8-Bit Bidirectional Binary Counter; 16-Pin (3-State)
    4) 74HC40103 5V 8-Bit Synchronous Binary Down Counter
    5) 74HCT40103 5V 8-Bit Synchronous Binary Down Counter; TTL Enabled

    I was looking at those first three chips, but the data sheets were kind of vauge on the cascading. I guess I'll play around with them until it works.
    the 193's can pretty much cascade infinatly, right now i am using 3 for a twelve bit set up, but I need to go to 16 bit and reduce chip count at the same time
    Thanks for input!

    Then I think microcontroller like 89C51 is the best solution. Cheap and easy! Just one chip and handfull of components will do the job.
