Summary: Why use XLISP when you can have Scheme

First, let me say a public thank you to David Betz for creating XLISP
over a year ago, thus making some sort of LISP available on practically
any small machine.

Now that I've said that, I want to tell you that the only virtue of
XLISP is that it will run on anything.  It is slow (being a straight
interpreter) and only slightly compatible with major LISP dialects.

My favorite LISPs are implementations of Scheme.  Some of these
implementations compile to native code, but the ones on low
end machines typically compile to a byte code, which is then
interpreted - this is faster than direct interpretation, but
slower than full compilation.

After IJCAI I posted a short list of where to find Scheme or
Scheme-based LISPs.  Its now out of date, but I'll post it again
in a followup article.  The PC-Scheme from TI is now done, and
you can get MIT-Scheme either by FTP from the Arpanet, or from
the GNU distribution.  Also, there's an Arpa mailing list for
Scheme discussion.
