Hi, I just found full source codes of perhaps the first computer algebra system (CAS) ever, Schoonschip from 1963 by M. Veltman [1] (and improvements later by other people), that's 52 years ago:
http://www-personal.umich.edu/~williams/archive/schoonschip/index.html See the source code: http://www-personal.umich.edu/~williams/archive/schoonschip/SchipSrc-CR.tar.gz written in assembly language... Moore info about the code: http://www-personal.umich.edu/~williams/archive/schoonschip/README.txt http://www-personal.umich.edu/~williams/archive/schoonschip/README-src.txt And a detailed manual: http://www-personal.umich.edu/~williams/archive/schoonschip/schipman.pdf The manual is especially interesting to see how the program was used and what features it had, and it has lots of info how to implement tensors, gamma matrices etc. in particle physics. I think there is lots of stuff to learn from it, I am going to read it carefully. Veltman himself talks about the code on the page 4 at [2].
