It's a little disingenuous for Franz to claim any credit for Nichimen. Nichimen N-Graphics was the spinoff of the Symbolics S-Graphics system, written in ZetaLisp. Symbolics ceased new development and there were customers for the graphics system, so it needed to be ported to a Lisp environment that would run on available hardware.

> Franz Allegro CL is a further development of Maclisp You are completely wrong. "Franz Lisp" was written to be compatible with Maclisp so that it could run Vaxima. "Allegro Common Lisp" was written from scratch with no relation to Franz Lisp or Maclisp.
