Code variation 1 of 10Related to an advanced feature

The advanced versions of Elite have an extra edge count for the ship colour; Transporters are shown in cyan.

Code variation 2 of 10Related to the BBC Micro disc version

The ship hangar in the disc version displays the Transporter with normals scaled with a factor of 4, rather than the scale factor of 2 used in the other versions, but the face normals themselves are unchanged. I'm not entirely sure why.

Code variation 3 of 10Related to the BBC Micro disc version

The ship hangar in the disc version displays the Transporter with slightly different visibility settings to the other enhanced versions (the visibility settings are lower). I'm not entirely sure why.
