At Jetmax, they are still working on the Boeing 777 setup. The company is a daughter of Flightdeck Solutions to sell compact, modular, and ready-to-use 737 cockpit replicas, or a part of it.
Due to a lack of room for a complete flightdeck, or because you want a realistic homecockpit solution that can makes the job with just one computer, Jetmax has a 737 solution today, and another for the 777 in the future.
The 777 is ready since 2014 already! Waiting for mine to arrive in 3 weeks!
