Topo I was the first Topo Model sold. He was just a radio controlled robot. But, the commands came from an Apple II computer. There were working models for Atari and Commadore computers. Analog Topo was quickly replaced by Digital Topo or Topo II. Many of the TOPO I's were returned and sold without the control electronics for $125.00 as is. To tell if your Topo I is a real one, it should have a serial number in the arm pocket. Better yet, you should have the transmiter and Apple interface card!
