I still remember playing with one of those in a toy store when I was little. I wasn't able to talk the folks into letting me bring one home, though.
I do remember another thing I spent a lot of time with. When I was about six or seven I had lots of Star Wars men. One day my dad came home with a big (and I mean bigger than I was) Styrofoam box half, which had dozens of different sized compartments. I believed it may have been from an outboard motor. Anyway, dad got a knife and cut doorways between all the compartments, making it the worlds largest Star Wars play set. That was pretty neat.
Ah, the most important "toy" we had growing up- imagination. With imagination, lots of mundane, every day items became what ever we wanted them to be.
