Lisp Machine Inc, the former Los Angeles company that is a licensee of Texas Instruments’ NuBus architecture and artificial intelligence processor technology has filed for Chapter XI bankruptcy protection – and Data General Corp says that it is weighing up a bid for the company. Lisp, now apparently relocated to Lowell, Massachusetts, manufactures and sells the Lambda dedicated Lisp language workstation, but has been hit by a trend in the artificial intelligence community away from specialised hardware – and even languages, and towards up-coming languages like C running on standard off-the-shelf hardware.
