Back in December of 2016, I posted the success story of my D.I.Y. FSX Yoke and Rudder Pedals, which I have been flying for years now. It was based on the MJoy USB Project whereby I learned a lot about exactly what "controls" I really needed to fly, verses what I wanted on my flight control fixture.
Recently, I had the good fortune to try out a CH Products Yoke and Rudder Pedals, also both connected by a USB interface, actually I repaired issues in both these well used devices. As I checked all the features of the CH Products, I grew to like the Point-Of-View HAT Switch and wondered if my homemade controller had such a feature already built into it that I did not take advantage of? Well, it does!
Thus, came the revision 6 of my MJoy 1.3 Yoke, based on an old Radios Shack "switch-type" joystick and let me tell you, it works fine!
The attached zip file contains all the documentation I have on the subject as well as the original firmware MJoy13.ASM file that has served me well all the hours of flying FSX.
