KEYBOARD TEST SCREEN
Purpose: To test the POKEY, the ANTIC and ROM chips.
Format: A full keyboard displays. Press each keyboard key. The corresponding key on the
screen should change to inverse video. It should
change back to the original color when the key is

and then back. As each key (except RESET) is
pressed, a tone is generated.
NOTE: The BREAK key does not change appearance
or generate a note when pressed.
