muLISP is a LISP development system for CP/M that was later ported to the Apple II, TRS-DOS and PC-DOS. It was marketed by Microsoft Corporation from the late 70s up to the late 80s, during the last few years under the name Microsoft LISP. In addition to an interpreter and compiler the system includes an editor with a WordStar-like command set, a symbolic debugger (early versions had a simpler trace-debug package), a collection of libraries, and in later versions a tutorial and example programs. Note that some versions of the package bundled a compiler while others did not.
Around 1990 the company added a protected mode DOS version that ran on 80386 and higher processors called muLISP XM, Common Lisp compatibility (not quite complete) and CLOS, in addition to odds and ends such as a windowing library & manager, but there never was an official port of the package to either OS/2 or MS Windows. As muLISP was used as the basis for a number of scientific software and hardware packages it was sold and supported until about 2005 even though it had seen little or no development since about 1990.
