[Posted to comp.lang.pop, comp.lang.lisp and comp.lang.prolog]
An easily extendable mini-eliza written in Pop-11 was developed as a
demonstration forming part of an introductory AI programming course,
many years ago (around 1978) at Sussex University. Since then, it has
been used for teaching in various modified versions.
Thanks to help from colleagues who understand web scripting I have now
made a variant of this version of Eliza available on the web using
php.
You can try it here:
http://www.cs.bham.ac.uk/research/poplog/eliza/eliza.php
The pop-11 source code is here:
http://www.cs.bham.ac.uk/research/poplog/eliza/cgi-bin/eliza2.p
http://www.cs.bham.ac.uk/research/poplog/lib/eliza1.p
(about 53 kilobytes)

This version of Eliza will not run without poplog
http://www.cs.bham.ac.uk/research/poplog/freepoplog.html
It's a messy program first written around 1978 and extended by many
people since then. The programming style should not be taken as a model
of AI programming!
Perhaps it will be re-written one day.
Note: this version of Eliza has no memory: each interaction is
self-contained, and the occasional appearance of coherence is
purely illusory. All the rules are shuffled on every run, so
the same input can produce varied responses.
The Pop-11 pattern matcher makes writing rules very easy.
Pop-11 is available free of charge, with open source, as part of the
poplog multi-language system, including Pop-11, Prolog and Common Lisp,
from this site:
http://www.cs.bham.ac.uk/research/poplog/freepoplog.html
There is a version of poplog packaged for PC plus Linux available
here:
http://www.cs.bham.ac.uk/research/poplog/linux-cd/
along with a graphical toolkit, an agent toolkit, a vision
toolkit, and emacs conversion package for poplog.
A 20 Mbyte tar file can be downloaded to replicate the Poplog
configuration used at the University of Birmingham for teaching
and research:
http://www.cs.bham.ac.uk/research/poplog/bham-linux-poplog.tar.gz
Instructions are included, and start with this file:
http://www.cs.bham.ac.uk/research/poplog/linux-cd/AREADME.txt
The tar file is configured to go on a CD for AI students at
Birmingham. It has been tested on various versions of Linux
including RedHat 7.1, 7.2, 7.3, and Mandrake 8.2, but should
work on others.
It runs on a variety of unix/linux platforms and on windows, but at
present the windows version has no graphics
[Poplog was used on Windows NT with an X window emulation package in the
very successful Clementine data-mining system, developed by ISL and now
owned by www.spss.com. See
http://www.spss.com/spssbi/clementine/
Perhaps one day someone will make it work on windows without requiring
a commercial package to support the graphics.]
There's an online introduction to Pop-11 (a language similar in power to
Common Lisp, but with a more "familiar" syntax) here:

Comments, questions, suggestions, offers to work on Poplog may be
communicated to the comp.lang.pop news group.

Cool. It was originally written in Pop11 IIRC. Why not do the
scripting in pop11, Lisp or Prolog rather than PHP?
And are we to see Stroppy soon as well?
WELL?
BTW when we received Poplog in 1983, we decided that Stroppy's
insults were too mild and spiced them up. We replaced "Terry
Wogan fan" by "Richard Clayderman groupie", for example. Most
of the other replacements were too rude to print here.

Dalinian: Lisp. Java. Which one sounds sexier?
RevAaron: Definitely Lisp. Lisp conjures up images of hippy coders,
drugs,
sex, and rock & roll. Late nights at Berkeley, coding in Lisp fueled by
LSD.
Java evokes a vision of a stereotypical nerd, with no life or social
skills.

Good question. That's why I'm doing a "rival" version, that does do
the scripting in pop11. In fact, it's overdue, as I was going to
finish it last weekend. But life intervened. Maybe this weekend.

My version will have a (limited) memory. (Using hidden fields
in a form, rather than maintaining state on the server.)

That's horrible.
