1964 Jonny Quest S1E08 The Robot SPY

I was born in 1964 so, I didn't see the original broadcast of Jonny Quest. But, thankfully, I caught the re-broadcasts in the 1970s Saturday Morning Cartoons.
Here is Season One, Episode 8: The Robot Spy...
As Dr. Quest works on an revolutionary new weapon, Dr. Zin sends an advanced and unstoppable spider-like robot to examine it.
