I'm not that certain of which aircraft sims were hooked up to this arrangement ... but think the good old Phantom was a probable candidate. That said, I don't remember seeing this scenery capability hooked up to the Wattisham Phantom sim when I had the opportunity to visit the Sim Wing in Sep 1980.
I seem to recall that when I visited Coningsby as a university cadet in late '74 that there was a visual model. However by the time I first flew the beast in 1980, on the OCU at Coningsby and then later in the year at Wattisham (I joined 23 at much the same time as your visit) the visual model had gone.
I suspect there was no real justification for it once the aircraft went full time into the AD role.
