    [Do I have to do this?  I don't beleive in line eaters.]

    I have been pouring over data books trying to find an 8520.

    No banana.

    The closest thing I have found is the MC6820/MCS6520 in Osbornes
    book, An Introduction to Microcomputers.  The pinout is different.
    The pins and functions look close. The 6520/6820 is a PIA (Peripheral
    Interface Adapter).  I can only assume that the 8520 is also. If anyone
    has data sheets for the 8520, please send me a copy. I am trying to get 
    enough information to begin experimenting with devices hooked to the 
    parrallel port.

    I have a copy of the Amiga schematics called Schematics and Expansion
    Specifications.  (I appreciate Commodore making them available!!)
    The specifications outline the functions of the pins of the parallel
    connector,but I would like more nitty gritty about what I can
    do with the input and output of that port. 


    Please?


    P.S. The schematics for the Amiga are titled ZORRO in the Schematics
    and Expansion Specifications  manual.  Was that the original name?
