Drifting off topic a bit, but look what I found when looking at pictures of molex connectors. This looks an awful like the greeble on the AT-AT driver chest box.
I see that Mon Cal use a similar greeblie as the one you found on both comm pad and chest box.
Indeed, the greeblies on the chest box and comm pad could very well be the same type, but I am convinced that that Molex connector you and Mon Cal found is the wrong type for at least the comm pad.
which is used by both the imperial crew and the AT-ST drivers (not seen on screen)
I designed a belt buckle cover to be used on top of a the large Tandy belt buckle blank along with the compad. I uploaded the belt buckle to shapeways and updated the compad model slightly. I always sharpen the features a bit because the printing and paint process dulls them.
My brain is now in tune with this greeblie, Im rewatching ESB in 4k and im finding it everywhere... The base must be a stock part for ssomething since its used so frequently
Seems that the keypad of the greeblie in this version is attached on the back and has more terminations... I really believe its the saem piece just with more terminals
Ok the battle of hoth is over... lets keep watching.
