Just to clarify, this serial interface box that you've been given doesn't have much to do with ROBOLAB. ROBOLAB is the software for the RCX. What you want (free) is LEGO Engineer, which looks and smells a lot like ROBOLAB. (URL) Right now only the (...)

I bought one of those four years ago (long before Mindstorms). It's an absolutely wonderful unit - considerably better than the RCX, Scout, etc. The only downside is that it must be tethered to a PC (though you could buy a wireless serial (...)
