It goes even further, since all of IBM's mainframes also include emulators for
their previous machines (which I believe are the 704 and 1600).  Now adays,
the IBM 3084 emulating an IBM 704, runs faster than the original machine.  Some
of IBM's biggest customers run accounting programs written in the early 70's,
for which there is no source available (or the source is all assembler).
