[COFF] Smokin' In the Terminal Room

[Lars Brinkhoff]

Photos of the MIT AI lab PDP-6 has a sign with "NO SMOKING".  Some of
the hackers famously detested smoking, to the point of carrying around a
fan to divert smoke in restaurants.

Here we can see someone smoking, and maybe the sign was put up later.
