Keypad Game
By Spectre Systems
1983

This is a simple program to show you how to use the port values to access the 
SPECTRE keypad.  It compares what key is pressed to what square is selected.  
Press the left button to start and be ready to press the key that corresponds 
to the square with a box in it.  The scoring is similar to 'Get the Box.'  The 
lower the score the better.


Archiving Notes:

This program is for use with the Spectre Controller, which was created for use 
with the Astrocade cartridge ICBM ATTACK.

I have tested the program using a pair of Astrocade controllers to simulate the 
ICBM ATTACK controller.  I fixed an error in the BASIC listing for Keypad Game 
on line 40.  The BOX command should not be given the variable I twice, but 
rather two 8s.
