What was the name of the programmable tracked toy in the 80s?

Question

I remember having one of these toys in the 80s, it was fairly large had buttons on top to program it to move around. I think it had track or trak in the name, but I cant remember what it is called. Only that it was very cool!

Answer 1

Your right it was the Big Trak made by Milton Bradley in 1979. It also had a bucket dumping trailer accessory too that sold separately.
