Editing Lisp machine (section)

===End of the Lisp machines===
With the onset of an ''[[AI winter]]'' and the early beginnings of the [[microcomputer revolution]], which would sweep away the minicomputer and workstation makers, cheaper desktop PCs soon could run Lisp programs even faster than Lisp machines, with no use of special purpose hardware. Their high profit margin hardware business eliminated, most Lisp machine makers had gone out of business by the early 90s, leaving only software based firms like [[Lucid Inc.]] or hardware makers who had switched to software and services to avoid the crash. {{As of |2015|1}}, besides Xerox and TI, Symbolics is the only Lisp machine firm still operating, selling the [[Open Genera]] Lisp machine software environment and the [[Macsyma]] computer algebra system.<ref>{{cite web|url=http://www.lispmachine.net/symbolics.txt|title=symbolics.txt}}</ref><ref>{{cite web|url=http://fare.tunes.org/LispM.html|title=A few things I know about LISP Machines}}</ref>
