Ramtex Space Invaders / Block Buster (19??, LED, 4 AA Batteries,
Model# ?)
CPU: General Instruments PIC 1655A-081
This is Space Invaders / Block Buster by Ramtex. I have seen this game (and it's prequel Alien Invaders) sold under many different names (Kingsonic, Sinitron, R.E.L., Ramtex themselves...), and it's usually called Space Invaders / Block Buster or U.F.O. Invaders / Block Buster. (The only differences on the game are the two silver stickers at the top.) This game is similar to the first version (Alien Invaders), but it can also play a Block Buster game. Ramtex is the manufacturer, their name can be found imprinted on the circuit board inside the game. Interesting design, batteries load in the front and it has a little plastic stand that slides out on the bottom so the machine will stay balanced at an angle. It's kind of awkward to play (I think), the buttons aren't really laid out well.
Ramtex and Sinitron versions:
Do I have this? Yes, Kingsonic version loose and R.E.L. version boxed.
