The Lisp Machine wasn't simply a piece of hardware which happened to run Lisp: http://www.sts.tu-harburg.de/~r.f.moeller/symbolics-info/development-environment/index.html http://www.sts.tu-harburg.de/~r.f.moeller/symbolics-info/dev... http://www.sts.tu-harburg.de/~r.f.moeller/symbolics-info/docex/docex.html http://www.sts.tu-harburg.de/~r.f.moeller/symbolics-info/doc...
