Paramax business unit was separated from Lockheed Martin under the control of Frank Lanza (who had been Loral's president and CEO); and became a subsidiary of L-3 Communications. In 2019, L-3 Communications merged with Harris Corporation to form L3Harris Technologies. Software projects In the 1960s, SDC developed the timesharing system for the AN/FSQ-32 (Q32) mainframe computer for Advanced Research Projects Agency (ARPA). The Q-32 was one of the first systems to support both multiple users and inter-computer communications. Experiments with a dedicated modem connection to the TX-2 at the Massachusetts Institute of Technology led to computer communication applications such as e-mail. In the 1960s, SDC also developed the JOVIAL programming language (Jules' Own Version of the International Algorithmic Language, for Jules Schwartz) and the Time-Shared Data Management System (TDMS), an inverted file database system. Both were commonly used in real-time military systems. References Claude Baum, The System Builders: The Story of SDC, System Development Corp., Santa Monica, CA, 1981. .
