The machine is an IBM 7094 (or one of its relatives).  There were two
big banks of 18 switches and lights side by side.  The address register
and the data register.  The C stands for contents not current  I believe.
I was walking through the University of Maryland one day with one of the
MIT lisp hackers and we stumbled accross an old 7094 console and his eyes
got kind of misty and said "This is where it all began."
