subLogic flight simulator is even older (first Apple II version in 1979) https://youtu.be/uvvfJ60gIf0 Microsoft licensed it to make MS FS.
Someone showed me (subLogic) Flight Simulator II, on a C-64 I think before I had a computer. I finally got a used IBM PC as my first computer (4.77 MHz 8088, CGA graphics, 20 MB hard drive) and MS FS version 3 and played the hell out of it, despite how badly it ran. When I installed it at my mom’s work on a 386 with VGA it was like a whole new game.
I read through Don Eyles apollo memoir Sunburst and Luminary- great book. In the book he describes their simulator for the lunar landing (essentially a test harness for the landing code) which consisted of inputs of coordinates and speeds, and gave printed output of thrust changes and expected position over time. Mind blowing for someone so used to visual representations.
This is actually correct. You don't need visual fidelity for a good simulation, nor physical fidelity. The important thing is that your mind and your body goes through the motions. You don't need to actually believe you're doing the thing, just practise the motions, cognitively and physically.
I'm pretty sure it was from Microsoft. I may have even the paper instructions, i'll search for them :-) Wikipedia: "FS1 Flight Simulator is a 1979 video game published by Sublogic for the Apple II. A TRS-80 version followed in 1980. FS1 Flight Simulator is a flight simulator in the cockpit of a slightly modernized Sopwith Camel.[2] FS1 is the first in a line of simulations from Sublogic which, beginning in 1982, were also sold by Microsoft as Microsoft Flight Simulator."
