The Texas Instruments Explorer is a family of Lisp Machine computers. These computers were sold by Texas Instruments in the 1980s. The Explorer is based on a design from Lisp Machines Incorporated, which is based on the MIT Lisp Machine.

The Explorer was used for development and deployment of artificial-intelligence software. Later models were based on a special 32-bit microprocessor [1] developed by Texas Instruments, which supported the execution of Lisp software in hardware. The operating system of the Explorer was written in Lisp Machine Lisp and supported also Common Lisp.

Notable is also the early use of the Nubus as the system bus for the Explorer computer family.

Several models were available:

  • the Explorer
  • the Explorer II, based on the Lisp microprocessor
  • the Explorer LX, which combines the Explorer with a co-processor running a version of UNIX (TI System V)
  • the MicroExplorer, a Nubus board for the Apple Macintosh based on the Lisp microprocessor

A notable application is SPIKE,[2] the scheduling system for the Hubble Space Telescope. SPIKE was developed on Texas Instruments Explorer workstations.
