For more on #5 (original Fortran optimizing compiler), including the source code, see http://www.softwarepreservation.org/projects/FORTRAN/ http://www.softwarepreservation.org/projects/FORTRAN/ . For more on #7 (Quicksort), I especially recommend Hoare's paper in the Computer Journal, which explains many details about the algorithm that are unfortunately not widely known (such as the correct way to partition for Quicksort): http://comjnl.oxfordjournals.org/content/5/1/10.abstract http://comjnl.oxfordjournals.org/content/5/1/10.abstract (the full text is freely downloadable).
