Consider porting opentcp or lwip to your platform. If you are lucky
there is already a port available. The 68k's are not that popular
anymore (good old times when I had one of those in my first Atari
ST...), but chances are that there is a Coldfire port or such
available that is close enough. For the ethernet controller I
recommend you the cs8900a from cirrus logic. This chip is extremly
well documented and easy to interface.

The remaining part of the weather station - compared to make tcp ip
etc. work on the platform - should be a sidewalk. Oh, before I forget,
Don't miss to check out the slaa137 technote from ti describing a
little http server app based on one of their 8bit chips along with the
cirrus chip I mentioned (use google and search for slaa137). This also
contains a very straight foreward simple tcp implementation in c that
also should be very simple to port to your 86k (provided you have a c
compiler).

As the "operating system" I recommend you to take a state machine
aproach. By doing so you should get away with above port, some code to
query your weather sensors and you are done.
