sorry for reviving such an old thread, but I just got my Johnny 5 toy from eBay last weekend.
It looks totally like this model here, but it has a remote control to drive it (both chains controlled separately forward/backwards, turn upper body left/right) and the eyes light up. It's also "speaking" while moving.
There are small holes on the lower front side of the body for the speaker.
Can anybody tell me of the origin? Is it also from JOZ or Mike?
The seller (from Spain) told me, he bought it as a model kit many years ago, but the motors and electronics were included. It also has a professional battery space on the bottom (labeled with "9V"), so this has not been added later to a model without electronics.
