Here is the first electronic game I ever had, Missile Invader by Bandai Electronics. It was this, then a Binatone TV Master Mk8, then a Commodore Plus/4I found this one on Ebay for not much, it's so obviously a version of Space Invaders, but I loved it up until I took it apart to see how it worked The unit is quite simple, there's a fire button on the side, and a power switch at the bottom left, and two buttons for left and right next to that, there's a large LED screen, and they are full size LEDs with a plastic overlay on top, with a dual seven segment display at the top for your score Switching the unit on goes straight into the game, it always starts with the characters in the same places, meaning you have to move as soon as you switch on, or you get hit On the back is the battery compartment and the instruction label Close up of the label. It says you have to get the highest score you can with 50 shots, then the game ends and you have to turn it off and on again, however you can be hit infinite times without the game ending. You may notice the maximum score is 245 points, but the score display has only got two digits? Not sure how that works, as it's a hard game It takes a 9v battery, I bought one in anticipation of this being delivered, and it came with one already installed Here is the game in action, you are at the bottom and can move left or right and can fire only one missile at a time, the UFO is at the top and scrolls left or right, hitting this gives you five points, the invader in the middle moves randomly and fires one missile at a time back at you, if two missiles hit each other they are cancelled out, hitting the invader is hard as it keeps firing at you, and if you manage to hit it, you get one point, so you get more points for hitting the easier UFO, very strange! ?UNDEF'D FUNCTION ERROR
