Edwin A. Link would be thrilled at the advances made in processing, graphics and realism. He was a genius, the fact that he used the Organ Bellows principles to simulate roll, pitch and yaw was brilliant. He had a Theatre Organ in his home, sadly destroyed in the floods of 2011.
The Museum of Flight on Boeing Field which my wife volunteers at very frequently has a LINK trainer on display.
We have an actual pioneer who was a key player in PC flight simulation participating in this discussion. He worked with Bruce Artwick, the Sublogic Corporation and others. He has not mentioned it in this thread.
