So I started poking around inside my recently acquired 720 machine today.
I noticed a large brown paper bundle in the bottom of the machine. Curious as to what kind of garbage was included with the machine, I picked it up. It was somewhat heavy, and carefully wrapped/taped up. My mind immediatly ran through what it could be.
I take it to the workbench, and slowly begin unwrapping it. I couldn't believe my eye's!
There was a extra, 100% complete, NOS unused 720 controller carefully hidden away in the machine!
Here's a couple pics:


It never fails to amaze me what you find inside these old machines.

{edit} By the way, It is amazing how smoothly and solidly the unused stick turns, it is night and day different from the stick that is on the machine currently.{/edit}
