The full-motion Trident-3 sim near Biggin Hill is 30 years old this year. It's still running!
The mainframe is a Honeywell which was upgraded to RAM from CORE in the late 1970s, another box is a TI minicomputer, there is an Evans & Sutherland graphics generator, and a couple of BBC micros which are used to load the airfields & generate flight path displays for the instructor.
It's a real piece of both aviation and computing history, and also an extremely useful piece of equipment for both the Wannabe & ATPL wanting "refreshment". And best of all it's just 50 UKP per hour to hire.
