Now that the piggyback is no longer available from NLSA (Nova) for
the Labjack what is available that uses a USB interface?

Wayne replies:

It's very easy to build your own "piggback" adapter.  The SatPC32 web 
site shows how easy it is to build your own:

By the way, the new Labjack U3 is $30 cheaper than the now-discontinued 
U12.  The latest version of SatPC32 supports the U3.
