These drives where built on rubber mounts to reduce shock when the are moved for maintenance on their tracks.
6.
This is the input for that Halon gas that the drives where filled with while in operation. Halon gas is a deadly gas that is pumped into the drives that makes them fire-proof, if there was a fire, the room they where in would be filled with halon gas as well, giving any operators in the room only one minute to get out.
7.
This is the underside, the drives weighed 80-90 pounds, so they where put on tracks to slide on for maintenance.

With the cover off, we can see the armature heads and the cylinder.
