Between 1980 and 1982, I wrote a chess program for the hp41 pocket calculator, which is definetely the smallest fully working chess program in the world!
 

In order to run it, you need to download the hp41 emulator from ww.hp41.org

My program can be downloaded from the same site www.hp41.org

or directly from here

ENJOY!
