I have faint memories of having this space toy as a kid. It was late 70's or very early 80's. It was a sort of building kit that had all kinds of space ship parts. You could rebuild it into a working boat type thing, a spaceship, a car that rolled along, anything you could think of. It was modular, I remember the cockpit was white, it had pontoons for floating. It was battery powered, but I don't remember if it had a single battery pack or several for the different parts. Any guesses? I wonder if it was a microman set, as it had little micromanish guys, but I've never seen one just like it.
