Miscellaneous information and meta-information on LISP Machines, mostly small practical details not covered by other pages, for people who'd like to discover the fantastic lost world of LISP Machines.

While not strictly Lisp Machines, the Alto-descended Xerox workstations (the D-Machines) were the hosts for the Interlisp-D environment. This guy's Xerox Alto Archive has loads of documentation on the Alto and Mesa, its microcode language.

The Symbolics Lisp User's Group mailing list archives and information. SLUG is the ideal mailing list to join if you work with Lisp Machines, especially Symbolics ones. Many Lisp hackers still subscribe, including current and ex-employees of the company, and your technical and historical questions are quickly answered.

Ralf Möller's extensive collection of Symbolics LispM information, including hardware photos, exhibitions of both system and application software (including screen captures), pointers (locatives) to other online collections, some assorted information on competitive LispM systems, and some useful hacks for Genera (including a mouse acceleration hack).

Good pictures of Dan Moniz's Symbolics XL1200. Gives a good sense of scale of this VME bus and Ivory processor system, Symbolics's fastest hardware offering.

A draft of a paper by P. T. Withington investigating the Lisp Machine and how it both succeeded and failed in the face of the RISC workstation revolution. Also a good introduction to what a Lisp Machine is and why they were invented.

The extended abstract of an unpublished paper (the header is a fib, it was pulled at the last minute) on the design and implementation of the Symbolics VLM, a virtual machine implementing the Symbolics Ivory architecture on the DEC Alpha systems.

Information on the TI S1500 Unix machine and its sibling the TI Explorer Lisp Machine.

A document describing and giving schematics for converting a Xerox optical mouse for use with a Symbolics LispM. More useful today for Symbolics users who need technical information on their mouse connector and how to go about attaching other pointing devices in its place.
