From the Pitsco-Dacta online catalog, the current version of ROBOLAB ver 2.0 is W90051 and is called 'ROBOLAB Investigator'. It includes the Programmer software (which I hope is the full version). It costs US$59.00. But the catalog material is sort (...) (25 years ago, 14-Feb-01, to lugnet.robotics.rcx)

Just out of pure curiosity: How many different programming languages for the RCX exists? Which is the easiest/most advanced/best? (I know this is a matter of taste) And is there any language that does *not* use the LEGO firmware? --Tobias (25 years ago, 14-Feb-01, to lugnet.robotics.rcx)

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 (...)
