The 8520 is a custom Commodore part for the Amiga famaily made by the
MOS Technology branch of Commodore.  You can order one as a replacement
part through a Commodore dealer that offers Amiga service.

However you might want to consider using a 6526 instead.  This is the
the part that served as the basis for the 8520, is used in every C64
and is readily available from Jameco and firms offering "C64 parts".
The biggest difference it that it has a "decimal" time of day counter
rather than binary.
