Who remembers Unix V6?

Ah, life was simpler then...

There was a time when users where tickled to hold Eliza-like conversations with the Bourne shell, running on a PDP 11/34 with 512Kb actual core memory and 8Mb of on-line disk. (Don't laugh! 8-12 simultaneous users doing real work on a system with less grunt than a contemporary MP3 player. Back when men were real men, ...)

% light?
light? - no match!
%    

The '%' in the above was the standard prompt for ordinary users. The '?' was treated as a single character wildcard by the shell. And the "no match" was the shell's error response. (I vaguely recall that "wild card expansion" was handled by a binary exec'd by /bin/sh. Ah, for those modular days and Unix principles ... before Micro$oft began defining an OS as EVERYTHING UNDER THE SUN!)
