In brief, there was no way found to salvage it.
Airbus wanted the building back, and there was no way the sim could have been dismantled, moved and brought back to life (never mind the cost). Ask the people who maintained it about the black magic needed to keep it running even when it was still in place.
So the cab was taken off the moving base and moved to Brooklands museum in two sections, where it still is.
This is not rumour... I sat in it, in May '05. Last I saw it was October '06, when university students were working on the first steps of bringing some of it back to life.
I have no idea what happended to the rest of the equipment...
What pancho saw in the BA training centre Cranebank at LHR, was probably the external visual system, which BA recovered, because it was not specifically Concorde, so it could be re-used.
