ACM 6.0[0] is a heavily extended fork made by Umberto Salsi[1] (since 2008 and maintained until now) from original ACM 5.0 developed by Riley Rainey. > Riley Rainey founded Web Simulations in August 1997. > Back in 1991, Riley released the first free multiplayer air combat simulation for UNIX systems, ACM. He enhanced the program over time -- in 1996 it was integrated with the U.S. Department of Defense sponsored Distributed Interactive Simulation protocol (DIS). Integration with DIS allows ACM to interact with simulations written by a variety of defense contractors. > Now Web Simulations is bringing this technology to the rest of the world. Original ACM 5.0 developed until 2000: firstly as commercial software (binary and source code) for Windows, but later released as FLOSS app for UNIX (where source code was rewritten from Visual C++ to pure C).[2,3] FTR, Linux packages build from original ACM 5.0 source still included in all popular Linux distributions.[4] P.S. There is also GNU ACM 5.1 - another fork made by GNU/FSF devs from original ACM 5.0, but it was never included as package in Linux distributions and not updated since 2011.[5,6] [0] http://www.icosaedro.it/acm/manual/acmdoc-basic.htm http://www.icosaedro.it/acm/manual/acmdoc-basic.htm [1] http://www.icosaedro.it/en-index.html http://www.icosaedro.it/en-index.html [2] http://web.archive.org/web/19981206125848/http://www.websimulations.com/acmfw.htm http://web.archive.org/web/19981206125848/http://www.websimu...
