Lisp Machines weren't that successful. I was their target user, and I ditched Symbolics to use Lucid on Suns at the first opportunity. The Lisp Machine software was appallingly baroque. Everything had every possible feature. There was no design, just implementation, and lots of it. The manuals took up a whole shelf, and it was generally faster to write something yourself than to find the predefined function that did it. A lot of (arguably most of) the badness of Common Lisp is Lisp Machine culture showing through.
