Master and slave.... The one is a dual core Pentium 4 with 3 GHz. The other a Pentium 3 with 700 MHz. I admit these are quite unequal twins but each one fits to its purpose. The faster runs the Microsoft flight simulator, the slower some additional software for the instruments.
Thanks to WideFS both can communicate with eachother. Today I installed the Instructor Station demo from Project Magenta to test the link between the two. I think I will buy the full version because the software is great! You can play God with it... engine failure? Here it is... just click a button.
