Wow, that brings back memories!

First saw the C compiler sources on Geoff Steckel (local guru)'s desk around 1973 at the Harvard graduate computing center, and was absolutely floored at this fascinating-looking language. (Harvard got the first Unix tapes outside of Bell Labs; not sure of the connection there.)

All upper-case, of course, as the DEC lineprinters didn't have lower case yet. Real upper case was struck-through upper.
