One computer should run Aerowinx Precision Simulator, PS1IPC and IPC32. The other computer should run FS98, FS6IPC.DLL and the SceneryInjector. All control inputs are made to PS1.2; FS is simply the scenery generator.
Only Scenery Injector versions 1.00.xxxx are valid with PS1.2. From Jan 2000, no further work or support is available for these versions. The Scenery Injector for PS1.2 is provided for historical reasons, and for users that are awaiting their PS1.3 upgrade!
