I have written a version of Scheme which conforms to R3RS.
It has a few enhancements such as first-class environments and
dynamic-wind.  It is written entirely in assembly language;
the code file is approx. 70k.  It requires about 250k
to run, and you may dynamically re-size the storage.

Bad points: 

    * It currently only supports 32-bit signed fixnums.

    * No debugger (but you can install a dynamically-wound-in
      error handler which receives a continuation of the
      procedure at the point of the fault).

    * No compiler

It will probably be about 1 month before this is ready to
go out.  I would like to extend the number system, but am
afraid that will take a lot of time.  It will be
whatever-you-please-ware.
