Other Lisps for PCs include:
   o  UO-LISP from Calcode Systems, e-mail:calcode![e-mail]
      It comes complete with compiler and interpreter, and is optimised for
      large programs.  It is Standard LISP, not Common LISP. They are based
      in Amoroso Place in Venice, CA.
   o  LISP/88 v1.0. Gotten from Norell Data Systems, 3400 Wilshire Blvd,
      Los Angeles, CA 90010, in 1983. They may or may not still exist.
   o  IQLisp. Not a Common Lisp but still very good for PCs - you can
      actually get a lot done in 640K.  The lisp itself runs in less than
      128K and every cons cell takes only 6 bytes.  Unfortunately that
      makes the 640K (maybe a little more, but certainly no more than 1M)
      limit really hard. It has a byte code compiler which costs extra.
      This has support for all sorts of PC specific things.
      It costs $175 w/o compiler, $275 with.

[4-2]   Free Scheme implementations.

Repositories of Scheme source code are described in the answer to
question [6-2].

Remember, when ftping compressed or compacted files (.Z, .arc, .fit,
etc.) to use binary mode for retrieving the files.

   Many free Scheme implementations are available from altdorf.ai.mit.edu
   [18.43.0.246]. See also the Scheme Repository described below.

   The Scheme Repository contains a Scheme bibliography, copies
   of the R4RS report, sample Scheme code for a variety of
   purposes, several utilities, and some implementations. The
   repository is maintained by Ozan S. Yigit, [e-mail].
   The repository is accessible by anonymous ftp at
   nexus.yorku.ca [130.63.9.66] in the directory pub/scheme/.

   PC-Scheme, free by anonymous ftp from altdorf.ai.mit.edu in the
   directory /archive/pc-scheme/.  Written by Texas Instruments. Runs on
   MS-DOS 286/386 IBM PCs and compatibles.  Includes an optimizing
   compiler, an emacs-like editor, inspector, debugger, performance
   testing, foreign function interface, window system and an
   object-oriented subsystem.  Conforms to the Revised^3 Report on
   Scheme. Also supports the dialect used in Abelson and Sussman's SICP.
   The official commercialized implementation costs $95 and includes a
   reference manual and user's guide. Write to: Texas Instruments, 12501
   Research Boulevard, MS 2151, Austin, TX 78759 and order TI Part number
   #2537900-0001, or call 1-800-TI-PARTS and order it using your Visa or
   Mastercard.  [NOTE: Ibuki announced on July 13, 1992, that it has
   purchased the rights to PC Scheme from TI and intends to make it also
   available on 486 PCs and under Windows 3.1. For more information,
   contact IBUKI, PO Box 1627, Los Altos, CA 94022, phone [phone],
   fax [phone], email [e-mail].]

   PCS/Geneva is a cleaned-up version of Texas Instrument's PC Scheme
   developed at the University of Geneva. The main extensions to PC
   Scheme are 486 support, BGI graphics, LIM-EMS pagination support, line
   editing, and assmebly-level interfacing. (TI's PC Scheme gives users
   full Revised^3 support along with many primitives for DOS, Graphics
   and Text Windows. A powerful built-in optimizing compiler produces
   fast code.) The beta version of PCS/Geneva has been tested on XTs,
   ATs, AT386s and AT486s under various DOS and OS/2 versions. It
   even runs on Hewlett-Packard's HP95LX. To receive a copy of
   PCS/Geneva, please send email to [e-mail]. You will be
   given instructions on obtaining PCS/Geneva by FTP. Even if you ftp
   it from uni2a.unige.ch, you will need to send email to them to get the
   password necessary to uncompress it. The purpose of the mailing detour
   is to keep track of the users and diffuse bug reports along with
   corrections.

[4-4]   Other Commercial Lisp-like Language implementations.

   Le-Lisp includes a compiler, color and graphic output, a debugger, a
   pretty printer, performance analysis tools, tracing, and incremental
   execution. Le-Lisp is Macintosh AUX 2.0 Compatible and also runs on
   Unix platforms. Note that Le-Lisp is neither Common Lisp nor Scheme.
   Le-Lisp was originally developed in 1980 at Inria, the French national
   computer science laboratory, by a team led by Jerome Chailloux for
   work on VLSI design. It was based on several earlier Lisps in the
   MacLisp family, but was not directly derived from MacLisp.  Le-Lisp
   enjoyed a large success in the French academic world because it was
   small, fast, and portable, being based on a abstract machine language
   called LLM3.  In 1983, for example, Le-Lisp ran on Z-80 machines
   running CP/M. In 1987, Ilog was formed as an offshoot of Inria to
   commercialize and improve Le-Lisp and several products which had been
   developed with it, including a portable graphic interface system and an
   expert system shell.  Since then, Ilog has continued to grow and
   expand the use of Le-Lisp into industrial markets around the world.
   Ilog is the largest European Lisp vendor, and continues to develop new
   products and markets for Lisp.  In 1992, Ilog released the next major
   version of Le-Lisp, Le-Lisp version 16.  This version modernizes
   Le-Lisp for use in the industrial world, adding lexical closures and
   special-form-based semantics for static analysis, a new object system

[4-5] Where can I get an implementation of Prolog in Lisp?

Implementations of Prolog in Lisp:

   The Frolic package from the University of Utah is written in Common Lisp
   and available by anonymous ftp from cs.utah.edu:pub/frolic.tar.Z

   Prolog in Scheme is a collection of macros that expand syntax for
   clauses, elations, and so on. It is written in Scheme and has support
   for delayed goals and interval arithmetic. It is known to run in Chez
   Scheme and in Elk, and is intended to be portable to other Scheme
   implementations. It relies on continuations, and so is not easily
   ported to Common Lisp. Available from the University of Calgary by
   anonymous ftp from
      fsa.cpsc.ucalgary.ca:pub/prolog1.2/prolog12.tar.Z
   Questions and comments may be addressed to Alan Dewar
   <[e-mail]> or John Cleary <[e-mail]>.

   An implementation of prolog for Chez Scheme is available by anonymous
   ftp from titan.rice.edu:public/slog.sh. It is a collection of macros
   that expand syntax for clauses, elations, and so on into pure Scheme.
   It should be easily portable to other Schemes.  Its use of
   higher-order continuations is probably a major obstacle to porting it
   to Common Lisp.  For more information, please contact the author:
   [e-mail].

   LM-PROLOG by Ken Kahn and Mats Carlsson is written in ZetaLisp and not
   easily portable to Common Lisp. It is available by anonymous ftp from
   sics.se:archives/lm-prolog.tar.Z.

   Peter Norvig's book "Paradigms of AI Programming" includes Common Lisp
   implementations of a prolog interpreter and compiler. The software is
   available by anonymous ftp from unix.sri.com:pub/norvig and on disk in
   Macintosh or DOS format from the publisher, Morgan Kaufmann.  For more
   information, contact: Morgan Kaufmann, Dept. P1, 2929 Campus Drive, Suite
   260, San Mateo CA 94403, [phone]; FAX: [phone]

   Harlequin's LispWorks comes with Common Prolog -- a fast
   Edinburgh-compatible Prolog integrated with Common Lisp.  Write to:
   Harlequin Limited, Barrington Hall, Barrington, Cambridge, CB2 5RG, call
   0223 872522 (or 44223 872522 outside UK), telex 818440 harlqn g, fax 0223

[4-6] What is Dylan?

Dylan is a new object-oriented dynamic language (oodl), based on Scheme, CLOS,
and Smalltalk.  The purpose of the language is to retain the benefits of oodls
and also allow efficient application delivery.  The design stressed keeping
Dylan small and consistent, while allowing a high degree of expressiveness. A
manual/specification for the language is available from Apple Computer.  Send
email to [e-mail] or write to Apple Computer, 1
Main Street, Cambridge, MA 02142.  Include your complete address and also a
phone number (the phone number is especially important for anyone outside the
US). Comments on Dylan can be sent to the internet mail address
[e-mail].
