This micro-computer has connected (not-detachable) two Hand Controllers with coil wires.
Every Hand Controller has a keyboard with 12 buttons. These buttons are used to feed data to the
micro-computer.
Some Game Cartridges are supplied with Overlay (s), to be inserted onto the keyboard (s).
To mount the Overlay over the keyboard, insert the upper side of the Overlay into the upper side of the
keyboard, then bend it down and insert the lower side of the Overlay into the lower side of the keyboard
(see fig 2)
Every overlay matches the particular game to be played and indicates which button of the keyboard is
operated to control the game.
Some cartridges are supplied with two overlays for two players, indicating in which keyboard they should
be inserted.
There is one ACTION button on each side of every Hand Controller. They perform the same function for the
convenience of either right or left hand player.
The function of the keybaord depends on the cartridge being used and is different in every cartridge.
The Control Disc on the lower side of the Hand Controller is to control the direction of the moving object on
the screen.
Example: By pressing the lower edge of the disc, or pulling the Joy Stick to the lower side of the disc, the
object will move to the lower side of the screen and so forth.
To stop the motion of the object, just release the disc or the Joy Stick.
