Mastermind © 1980 Fabris, Robert.
In this version of 'Mastermind', the computer holds a four-color code that you must guess. Enter the first letter of each color guessed via the keypad. Each BLACK response means a correct color in the correct spot, a WHITE response means a correct color in the wrong spot.
