Thank you Belloq Tull for your suggestion. It takes already having the needed item to do that test. Fortunately, I have a few that a friend gave to me. It seems that shield cannot be properly equipped. It can just be stowed inside a container.
Dail Llwybr Gwaed,
Just a little anecdotal thing. I have a T7 Series Astromech
droid. According to the droids
page, that droid is still unimplemented. Despite of that, I place it at the cockpit of my ship, get out of it and board a docked ship. This used to stop the ship from moving. With the T7 at the cockpit, it continues moving. So it is at least partially implemented. The red X is outdated. So I don't trust those little read Xs.
