As Eric said, the 2005 Operator interface is compatible with the 2006 Robot Controller, and the code is stored in the Robot Controller. The latter fact probably won't be of much use to you, however, as the code is only stored in compiled form. You can use a special tool to extract it from the robot for back up purposes, but you won't be able to read or edit it unless you're keen on working in PIC assembly or running it through a decompiler and trying to make sense of it. If your team doesn't have the source code for the old robot, your only option is to start from scratch with the 2006 default code.
