I'm almost positive there was a RAT to keep hydraulics for the flight

Yes, same on the Airbus. However, on both the 767 (Gimli) and A330 (Air
Transat) the RAT only provided enough hydraulic power to drive the
primary flight controls and brakes, so both landed 'hot' with no flaps
deployed.

One account I read said the A330 had 30 mins battery backup for its glass
cockpit and radios. It landed after 19 minutes on glide. The Gimli 767's
glass cockpit quit with the engines, leaving just basic mechanical
instruments for navigation and landing, so they were lucky that P2 knew
the area and that the radios had backup batteries.
