I'm looking for information on a software package, REDUCE2LISP, that was
included in a collection known as the "A Series Higher Education
Software Library" (HESL20) tape that was released by Burroughs ca. 1985.

REDUCE2LISP was an implementation of Standard Lisp and the REDUCE
symbolic equation manipulation system, originally developed by Hearn,
Griss, and others at the University of Utah during the 1970s and 1980s.

I have a copy of the files from that tape, and one piece of
documentation states this:

"The algebraic processor was largely written by Anthony Hearn, the
compiler is the work of Anthony Hearn and Martin Griss, the assembler
was done by John Fitch, the part of the LISP processor written in
RLISP was done by John Fitch and Jed Marti. The integration package
was developed at Cambridge by Arthur Norman, John Fitch, and Maryann
Moore. The ALGOL portion of the LISP processor, originally an SDL
program for the B1700 that was written by Fitch and Marti, was
translated to ALGOL and subsequently modified by Dave Dahm."

Does anyone know anything about this package? I'm particularly
interested in knowing how the initial implementation got started on the
B1700, what prompted the conversion to ALGOL, and how Dave Dahm may have
gotten involved with it.

If anyone is interested in the HESL20 files, you can download them as
PWB (Windows ASCII) text files from here:
