Jim McLucas retired from Hewlett-Packard Company after 30 years working in production engineering (analog and digital voltmeters) for 4 years, then production engineering for both hybrid and integrated circuits for 5 years, then on design and test of analog and digital circuits. He specialized in design of switching power supplies and previously worked for Westinghouse Defense Electronics for 3 years on design of frequency synthesizers.
