Tadpole as company was launched back in the last century (early 1990s?). It was taken over General Dynamics in 2005. In the same year General Dynamics acquired Itronix. It looks like these acquisitions never really fitted into the large company structure of General Dynamics and they pulled the plug on the product lines in 2013. Support for the existing products was taken over by Flextronics.
I've put the Pulsar under the Tadpole name as it was a Tadpole product, and also I cannot fit 'General Dynamics' onto the button in the left-hand column!
