Info: BIG TRAK / bigtrak is a programmable toy electric vehicle created by Milton Bradley in 1979, resembling a futuristic Sci-Fi tank / utility vehicle. The original Big Trak was a six-wheeled (two-wheel drive) tank with a front-mounted blue "photon beam" headlamp, and a keypad on top. The toy could remember up to 16 commands, which it then executed in sequence. There also was an optional cargo trailer accessory, with the UK version being white to match its colour scheme; once hooked to the Bigtrak, this trailer could be programmed to dump its payload.
