This was the exact arcade I grew up on! We had one at our local Asda. Mum would go shopping and leave me to play this Space Invader. This was the US version of Space Invaders with buttons not the joystick version that was Japanese. The cabinets were also different. The Japanese Taito one red and different shape cabinet.
For me it had to be the blue Space Invader with buttons left and right.
This one is totally original. It has the moon effect, great sounds, marquee all lights up. Of course its 42 years old now so has the odd scratch and bump. Nothing serious. To be honest it adds to the character of the arcade.
So all ready to go to a new home. The iconic SPACE INVADERS. Every home should have one!
