I am reminded that Gretag AG ( Swiss ) now Gretacode/Omnisec made type 4 STU-3 ; partner of U.S. company Datotek ( Farmers Branch / Realty Rd; Dallas TX ) : modified the CSD-4100 phone. Now see http://www.tccsecure.comWest Concord MA USA. TCC and Datotek were arch rivals and Datotek buckled. Datotek founded by ex Texas Instruments folks. Also be aware of Motorola Sectel 9600. It is wild how Govt influences others! IBM , DEC-Digital Equipment Corp, HP, Data General, SUN ( now Oracle ) , Wang Labs all made TEMPEST terminals and other equipment. Best wishes to all.
