I've talked to the creator of RCXcc about Scout support. This is what he had to say; Mark Overmars wrote: "This is not planned for the near future." There you have it.

(...) The datalog appears to work fine, and you still have the same amount of program/datalog space. There was a ton of unused RAM in the older firmware, so Lego was able to pack a lot of new features in without reducing the user space. Dave Baum (24 years ago, 8-May-00, to lugnet.robotics.rcx.nqc)
