The upper end model in Waimea
 

In order to facilitate the design of the cabling of the upper end, and to check the placement of the various components of MegaPrime on the prime focus environment base, a model has been built (at scale 1). Here are a few pictures of the model in the CFHT workshop in Waimea. 

If you click on the pictures, you will get an enlarged version with some  text detailing the various components of the upper end...
