IQLISP

A LISP implementation for DOS sold by a USA based company called "Integral Quality" in the early-mid 80s. It was considered a superior quality to other early LISP packages for the PC as far as language implementation and libraries were concerned but the pedestrian editor supplied and the lack of utilities was noted in most reviews. The company later offered an optional bytecode compiler for the system.
