I had a chance to do a short guest flight myself onboard the former east german MiG-29 cockpit simulator. It was still used then by the Luftwaffe evaluation squadron at Preschen back in 1991. This used a real model and a black and white TV set for outside forward views. No motion but rudder pressure. Surprisingly "real" given the very limited infrastructure. Everything was containerized and movable by trucks. So that one might likely have ended up at Laage.

I have seen a similar sim at Finow airbase north of Berlin in the early 90s which was still russian operated back then. They had two landscape models there. One for pattern work and another "endless" belt-type one for bomb runs.

P.S. Look at those turnout scratches behind the lower taxiway :)

One technician told me the same story about Lossiemouth with those small pop-up toys with the spring and suckers. On the final day of training the standard practice was to place one or more of those just behind a cliff edge. When the pilot flew 300 feet over the tree line and dropped down, that was the first thing he'd see. Bonus points if the toy jumped into the air at that moment. I can only imagine what one of the toys must have looked like when scaled up.
