No, the chair was destroyed. The platform itself is still operational.

That is exactly what I mean. Without the drone chair the weapons platform doesn't have a control base for any of its systems. That being said the ZPM previously powering the drone chair would effectively have no purpose so why would it not be installed on the SGC'S newest and most advanced ship.

Besides the chair is made of metals and such, as McKay so delicately puts in the episode where they are at the fake SGC ZPMS can't be broken easily, without some kind of mega explosion. The ZPM likely would of survived the Kamikazee.

That was never in dispute, though it was in Area 51 at the time to poeer the chair for the oncoming wraith attack it would no doubt survive the destruction from the darts. Since it likely survived and thd chair is no more they don't really have a better place for it.
