Tandy/Radio Shack / 1984 / Owner’s Manual PDF

I had one of these and loved it.  Recently I bought two on eBay because, yes, I “missed” it.  The construction is absolutely amazing – essentially a single motor runs a convoluted path of gears that changes as the user manipulates the joysticks.

Tomy / mid-1980s / Owner’s Manual PDF

I had one of these and loved it.  It used an audio cassette to record and then play back movement instructions and audio.  It has a remote control that operated its movements and also allowed the user to speak through it, which lit up the lights based on sound volume.  The arms were poseable and could hold cups, pencils, or a tray.
