Were do you get the software to program the old control system, the version before the current (CRIO) system.
You should be able to order it here: http://www.vexrobotics.com/products/programming
The default code and downloader are available at http://www.ifirobotics.com/rc.shtml#Programming.
A student version (still contains all necessary features, unless something has changed) of the compiler can be downloaded at http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en536656.
With that 3.x compiler you will need to start with code from Kevin Watson’s site.
