Wow, you must have been out of the loop for awhile! All castle escs are programable with a Castle Link. I imagine you must be refering to the Mamba Max as your old castle. The MM only needed a usb cable. Now you need a Castle Link or the field programing card. The card can be used on its own, no computer needed, and is very handy. However to use the castle link to program advance features you will need a windows PC :-( I just went out and bought a windows netbook two weeks ago so I can do that. Castle really should make a Apple friendly program
