@jmmijo, I played the original (floppy disk, XT with CGA colour graphics). I played it first at a friendīs house. After that I could get no rest till I put my hands on a PC. When I've got one, this was the first game I copied.
But now, I remember when I bought the PC (or better, when my father bought me one), it came with a few games like Digger and Alley Cat. A I remember also playing Firepower on it.
