Run Archi

The game is cracked, so for the code screen, just type any random series of numbers and press enter. 

You are in for one treat with this game. Irradicating mutant plants on a post nuclear apocalypse earth is a pretty good concept. And the music is incredibly creepy. According to MobyGames, it's PC speaker only. But I'm certain I hear the Tandy 3 voice sound playing, especially since it's not present on the CGA, EGA or VGA versions. And best yet, the music plays on the jr with no patching and no need to run a sound driver.

The ability to quit to DOS, however, appears to be broken, as it requires both f10 and break. While f10 works fine by pressing the function then the 0 key, when you need to confirm by pressing break, which is function and b on a jr, it does nothing, so a system shutdown is required.
