I bought one of these modules 5 years ago for a senior project, using a Milton Bradley Big Trak as the base, and the Polaroid module as the input. Steve Ciarcia's columns in Byte (no longer) had at least 2 project that used them, which has much information about how to use these systems. You can get these from one of these two sources: Circuit Cellar 4 Park St Vernon, CT 06066 (203) 875-2751 or Micromint 4 Park St Vernon, CT 06066 (203) 871-6170 (800) 635-3355 but these two sources are pretty close to being the same source. Try the 800 number first. -Dave Dave "mr question" McIntyre | "....say you're thinking about a plate mcintyre@turing.cs.rpi.edu | of shrimp.....and someone says to office : 518-276-8633 | you 'plate,' or 'shrimp'......"
