Fischertechnik Interface / Documentation?

I'm assisting in the construction and control of a robot for a competition with my highschool based around a "fischertechnik interface". I don't have any documentation or information on this interface, besides the fact that it's parallel port controlled and most of the control was done through various BASICS (C64, Apple 2, etc) I'm not even sure the documentation I have with the basic listings is for this interface. I'm hunting for information, but there isn't much avalable for this. The only real distinctive markings are "32372 - 1188 HD", FCC ID FZQ2WT UNIVERSAL... it's a black bottom with a clear plastic topped case, there's two sets of voltage inputs plus what appears to be a ground. there appears to be two parallel port pin headers? plus the header for output and motor control (four motor circuts) If it helps, there's a blank IC spot with "4050" in it. -- Gary G.
