Just found this video on Youtube where Pal, (predecessor of Johnny Five), was on Conan with excellent closeups & high def details. He was introduced as Johnny Five. This particularily interested me since I am fashioning my large robot, (Jazzy), on Pal's design.
Pal comes on stage about the 3 minute mark.
