    We would be interested in more info on Chez Scheme. Who can we contact ?
    Since we are using an experimental connection from New Zealand, please

Implementation:     Chez Scheme
Authored by:        Kent Dybvig
Supported by:       limited support by the author
Hardware:           VAX
Operating Systems:  4.2 BSD UNIX (or ULTRIX)
Implementation:     incrementally compiled to native code
Intended Use:       education and research
Price:		    Per site: $400 for US colleges and universities,
		    and $1000 for companies who will use the
		    system for research and education only.

Chez Scheme was first released earlier this year and is now being used
at about 10 universities for classes and research.  Chez Scheme supports
almost all of the required and optional features of the RRRS.  The next
major release (in spring or summer 1986) will support 100% of the
required features of the standard.

In addition to the features of the RRRS, Chez Scheme provides error and
exception handling, engines, programmable cafes and waiters (fancy
read-eval-print loops), tracing and statistics- gathering facilities,
and fast-loading compiled files.  Chez Scheme provides floating point
numbers, arbitrary-precision ratios, and arbitrary-precision integers,
but no imaginary numbers at this time.

Chez Scheme's biggest claim to fame is the speed and size of its
implementation.  It outperforms Franz Lisp and DEC Common Lisp on most
programs, but the initial core image is less than 500K bytes, about half
of which is read-only and sharable.
