In the early days of workable PC's, the BCS did a benchmark comparison of the technical typesetters then on the market. The American Math Society published the results in the Notices. As a new PhD, I was impressed with TeX's ability to handle anything they could throw at it.
As part of doing CTAN, I redid this document in LaTeX (it was originally done in plain TeX), with the permission of R Palais. Naturally I retained only the TeX part. Here is a PDF and a zip of the source. (The license is that my work is Public Domain; I can't speak for the original document.)
This site Joshua is run by Jim Hefferon and located in the Mathematics Department of Saint Michael's College in Colchester, Vermont USA.
Open Source software is a great idea. This project would not have gotten done without it.
