MAD (programming Language) - MAD, MAD/I, and GOM

MAD, MAD/I, and GOM

There are three MAD compilers:

1. Original MAD, the compiler developed in 1959 at the University of Michigan for the IBM 704 and later the IBM 709 and IBM 7090 mainframe computers running the University of Michigan Executive System (UMES) and the Compatible Time-Sharing System (CTSS) operating systems. In the mid-1960s MAD was ported at the University of Maryland to the UNIVAC 1108. Versions of MAD were also available for the Philco 210-211 and UNIVAC 1107.
2. MAD/I, an "extended" version of MAD for the IBM S/360 series of computers running under the Michigan Terminal System (MTS). Work on the new compiler started in 1965 as part of the ARPA sponsored CONCOMP project at the University of Michigan. As work progressed it gradually became clear that MAD/I was a new language independent of the original 7090 version of MAD.
3. GOM (Good Old MAD), a reimplementation of the original 7090 MAD for the IBM S/370 series of mainframe computers running the Michigan Terminal System (MTS). GOM was created in the early 1980s by Don Boettner at the University of Michigan Computing Center.
