  I have been unable to find any documentation or anything else useful to
  prove this, but I did use a Common Lisp system on TOPS-20.  It was an
  impressive system and among its most important features was that it could
  use a lot more of the available memory than most TOPS-20 applications,
  which were limited to 18 address bits, but this turned out to be a problem
  on a machine that was intended to support a lot of Emacs users, too.

Act from reason, and failure makes you rethink and study harder.
Act from faith, and failure makes you blame someone and push harder.
