Supervised student aides and junior programmers on a continuing basis, and groups of programmers on a project basis.
Computers used were GE Time Sharing System, Data General ECLIPSE C/330 under AOS and NOVA 840 under mapped RDOS; languages used were FORTRAN IV and FORTRAN5, and some use of GESIMTEL (a GPSS-like language).
1976 Part-time Instructor of Physics, College of San Mateo
1974 – 1976 Member of the Technical Staff, Computer Sciences Corporation, NASA Ames
Research Center, Moffett Field, CA 94035.
Work involved programming and running real-time simulations of aircraft and guidance systems in a state-of-the-art system with a pilot in the loop, using digital and analog computers, motion, visual, and sound systems; also conducting independent analyses and research to further clarify or upgrade the modeling techniques and software. Computers used were EAI 8400, XDS Sigma 7 and 8; languages used were FORTRAN IV and Xerox Extended FORTRAN IV.
