Hello Autopuzzlers,
It's been a while, but some of you might remember me, you poor unfortunate souls.
I've got a bit of a tricky one, though this group has a tendency to redefining just what is truly tricky. Still, it may be a challenge. Or not.
The only thing I know is that it made history a while ago (within past 50 years) and that it was created for a very specific purpose, one that it achieved. Beyond that, I have nothing other than some half-formed observations, a few hazy recollections, hints as-yet unexamined and woefully ill-developed thoughts. And my lunch is now cold.
