You had me going when I saw the word ``Nanotech`` LOL. Maybe Moxa or another ultra-long-timer can help me out here, but I seem to recall that PTSC originally got into the microprocessor world and all the Fish stuff/IP through the acquisition of/from a company in SD called ``NanoTech``. In fact, as I recall, way back they had a ``find our building`` map to guide you to PTSC HQ, which ended with a picture of a building with a ``NanoTech`` sign out front. Before the Nanotech move, PTSC was (I believe) solely in the SONAR and Ground Penetrating RADAR business (later sold).
