Geocache Description:

This is a small cache located on the UW-Madison Campus. Big enough to hold a dog tag travel bug. Bring your own pen. This cache is launching the Travel Bug BigTen Challenge (TB5K3QB). It is suppose to visit the 14 campus of the Big10 and then return to UW-Madison.

This specific cache recognizes a former co-worker. In randomanly discussing with him my distaste for LISP he stopped me and said, "Hay! I developed that". It taught me two things (1) becarefull what you bash and (2) greater respect for his technicial abilities. Eric Norman passed away a year ago and this cache is a way to memorialize him and his contributions.


LISP 1.5 for Univac 1108

"In the late 1960's, Eric Norman of the University of Wisconsin - Madison developed a LISP 1.5 dialect for the Univac 1100 series of mainframes ... .

The LISP system developed by Norman consisted of approximately 5,000 lines of Univac assembly language for the interpreter and about 1,000 lines or so of LISP for the compiler. Several interesting applications were developed under or ported to Univac LISP including:Planner (an early planning language designed by Carl Hewitt of MIT; MLISP (an Algol 60-like dialect of LISP); Fuzzy (a system that worked with Fuzzy Logic); and several LISP utilities such as a Pretty Print package, a Math Library, a source Editor, and a Debugger. The original source code for all of the above items -- including the full interpreter and compiler -- are contained herein and are discussed in some detail." [Jack Harper,http://www.frobenius.com/univac.htm]

"At the time, the Computing Center here at Wisconsin had decided to purchase a Univac 1108. It couldn't be delivered yet, though. What we had was a remote card reader and printer to an 1108 up in Minneapolis. Just about all the interpreter was developed that way. That is, I submitted a deck of cards at night and picked up the listings the next day. When the 1108 arrived on campus, LISP was already running on it." [Eric Norman, personal communication to Paul McJones, May 2005]


Congrats to 2CraziesMSN for the FTF and moving the Big10 Travel Bug along.
