| You need the 8U moduleYou need a module with the 8U -- it is the equivalent of the transmitter crystal, and the unit will not work without it.
The add-on memory is called a CamPac -- you do not need it. The 8U itself will store 8 models. The CamPac adds another 8, or you can use it to back up the ones in your 8U. |
