This version appears to be complete and ready for release. This
prototype is identical to the 400/800 release except the title screen
is missing the Atari copyright message at the bottom. It is unknown
why the 5200 version does not have this.
An undocumented feature allows the player to practice any event by pressing
the 1-6 keys. This is very handy when trying to qualify for the
later events like the Hammer Throw or High Jump.
