An 8520 chip spec was published in the 2nd Annual Amiga Developer's
Conference Notes which can be purchased from CATS Orders for $20.
The 8520 chip spec published in the Notes is adapted from the official 6526 
data sheet from MOS Technology. [It's a xerox with changes in a few places] 
The 6526 was the precursor to the 8520 and the chips are very similar in 
operation.
