Hey,
on page 269 of the Corebook there is a little sidebox about the useful programms a rigger can make use of, how they are only usable on a RCC and so on. But while searching i did find nothing as to how many programs an RCC can actually run. The part about device-rating and sharing explicitly names autosofts, and the drone-section only mentions each drone can run a number of autosofts or cyberprograms equal to its rating. Did i miss something here?
