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.
