The bits shown at the start of this mean it is in no way a projector of anything but that 'cylinder' thing (IMHO etc.); there's no
LCD or similar for the information to be shown on/projected from.
The FAST picture shows a 'screen' but there's no wires going to it.
I reckon the cable shown is just a power feed, but that's just a guess.
We (well, TT) have found references to what it is, but we're (I'm) still in the dark as to what it does.
Having said that, we're further forward now!
