Lisp Machine Keyboards

To understand the history of lisp machine keyboards, you must know some history of lisp machines.

Lisp Machines are computers (hardware) designed to run lisp programing language efficiently.

  1. CONS machine. First lisp machine. At MIT.
  2. 1974. CADR machine. 2nd generation of CONS. 25 prototype were sold.
  3. 1981. Symbolics LM-2, by Symbolics Inc. Commercial version of CADR. About 100 are made.
  4. 1981. LMI-CADR, commercial version of CADR by LMI (LMI is Lisp Machines Inc).
  5. 1983. Symbolics 3600.
  6. 1983. LMI-LAMBDA (about ~200 sold).
  7. Symbolics 3640, xl1200, MacIvory, and others.
  8. Texas Instruments, Explorer, MicroExplorer.
  9. Xerox, Innterlisp-D workstation. • Xerox 1100, Dolphin (1979) • Xerox 1132, Dorado • Xerox 1108, Dandelion (1981) • Xerox 1109, Dandetiger • Xerox 1186/6085, Daybreak

Lisp Machine pretty much stopped in 1990, due to, onset of Personal Computer that are cheaper and faster, and “AI Winter” (industry's failed expectation of AI research).

SAIL Keyboard

SAIL Keyboard. (SAIL = Stanford AI Lab. SAIL was started in 1963 by John McCarthy.)

The Knight Keyboard

This is the first lisp machine keyboard, probably took inspiration from the SAIL keyboard, because the color theme, and many keys and layout, are similar.

Knight keyboard. Made around 1974. This keyboard is used for the CADR Lisp Machine (and possibly also the CONS lisp machine)

CADR keyboard

This is used by Lisp Machine Inc's LMI-CADR, around 1981 and i think also by Symbolics LM-2 lisp machine.

Space-Cadet Keyboard

This is the famous Space-cadet Keyboard, year 1981.

It is the most famous lisp keyboard because its the most exotic.

Symbolics Keyboard PN 364000

This model is used with Symbolics 3600 machines. Year 1983.

Symbolics keyboard PN 365407

This model comes after the PN 364000, and is compatible to it. This is used in Symbolics 36xx series, perhaps around 1985.

Xerox 1109 lisp keyboard

This keyboard is for Xerox 1109 lisp machine. Year ~1982.
