The code is written in reasonably portable C. I know for sure it runs
on IBM PClones, Macs, and Amigas. The code is posted and occasionally
being discussed on BIX (Byte Information eXchange). The latest version
(as far as I know) is *very* preliminary, my copy is version 0.07. A
handful of bugs and lack of reasonable error messages makes it rather
unsuitable for real work at the moment, but a new and improved version
is rumoured to be in the works (though David Betz has been curiously
silent about it lately).
XScheme is based on a bytecode compiler. Apart from that, its
distinguishing feature is its object oriented extensions, similar to
those of XLisp.
