Try MTS: Exploring the Michigan Terminal System

Try MTS is a very nice, well done, independent web site, created by Rupert Lane in June 2014. It provides information about installing and running MTS under Hercules and an introduction to using MTS. Since 2014 Lane has continued to update the site with the addition of introductions to eleven (so far) of the programing languages available in the D6.0A version of MTS: BASIC, FORTRAN, MAD (GOM), ALGOL 60, ALGOL W, LISP, UTILISP, PL/1(F), SNOBOL, RATFOR, and FLECS. The most recent updates were made in early 2016.
