MACSYMA
A Computer Algebra System.From Bibliography on the MACSYMA, VAXIMA and maxima symbolic algebra languages (see below):
[..]MACSYMA, possibly the oldest surviving computer symbolic algebra system, was developed starting about 1968 at the Massachusetts Institute of Technology, using the MACLISP dialect of the Lisp programming language. The name stood for Project MAC's SYmbolic MAnipulation System, and MAC stands for Man and Computer, or for Machine Aided Cognition.
