MIMIC (1979)

Mimic (Memory Interfaced Micro Integrated Computer) is an electronic game similar to Simon. Colored LEDs light up in an ever increasing pattern, and the object is to "mimic" what has been shown each turn (and heard with beeps for each of the four colored buttons).
There are 3 play modes (1, 2, 3 -- not sure what these do) and 4 levels of difficulty (novice, amateur, junior, and pro) that can be set with two switches.
