===Artificial intelligence===
TI was active in the area of [[artificial intelligence]] in the 1980s. In addition to ongoing developments in speech and signal processing and recognition, it developed and sold the [[TI Explorer|Explorer]] computer family of [[Lisp machine]]s. For the Explorer, a special 32-bit Lisp microprocessor was developed, which was used in the Explorer II and the TI MicroExplorer (a Lisp Machine on a [[NuBus]] board for the Apple [[Macintosh]]). AI application software developed by TI for the Explorer included the gate assignment system for Northwest Airlines and United Airlines, [https://www.latimes.com/archives/la-xpm-1989-11-07-fi-1112-story.html described as]  "an artificial intelligence program that captures the combined experience and knowledge of a half-dozen United operations experts."  In software for the PC, they introduced "Personal Consultant", a rule-based [[expert system]] development tool and runtime engine, followed by "Personal Consultant Plus" written in the Lisp-like language from MIT known as [[Scheme (programming language)|Scheme]], and the natural language menu system NLMenu.<ref>{{Cite web|url=http://www.ti.com.cn/sc/docs/watson.htm|title=Texas Instruments|website=www.ti.com.cn|access-date=2016-07-26|url-status=live|archive-url=https://web.archive.org/web/20160817012717/http://www.ti.com.cn/sc/docs/watson.htm|archive-date=August 17, 2016|df=mdy-all}}</ref>
