You're just fine.  The first revision of the Buster chip had a bug in it; more
specifically, a missing term in one of the backplane buffer control signals.
Some of the very early units, mostly dealer demo and developer units, were
shipped with this Buster in a small tower board.  The tower board contains a
PAL that adds the missing term.  All later Buster chips have this corrected 
internally and as such have no need for a Buster tower board.  The Rev 4.2
sticker indicates your machine is fully up to date.
