> but it worked slower than using other languages minus Maclisp > Enter the late 80s; Lisp ran great on personal computers but implementations AFAIK were mostly commercial, so reserved to big budgets. CLISP, CMUCL, AKCL, XLisp, ... all were no cost. > SBCL and CCL SBCL is a fork of CMUCL which was started in 1981 as Spice Lisp. That was always no cost and several other projects took code and documentation from CMUCL. CCL is a free version of MCL - which was an affordable commercial Lisp for Macs in the end 80s.
