Apparently, this game was originally written outside of Digital, probably at a university. The game was ported to DEC's VAX/VMS from the TOPS-10/20 FORTRAN sources available around fall 1979. Ed James got hold of the sources at Berkeley and converted portions of the code to C, mostly to use curses for the screen handling. He published his modified sources on the net in December 1986. Because this game ran on VMS machines for so long, a previous version is known as VMS Empire. WWW: http://www.tuxedo.org/~esr/software.html
