The Mini TSFO (Training Set, Fire Observation) was the first artillery call-for-fire simulation designed for the personal computer. It was started in 1985 as an outgrowth of a Field Artillery Officer Advanced Course battlefield research project at the U.S. Army Field Artillery School (USAFAS) to develop a concept for incorporating PCs into artillery training, and was completed in 1986. It replaced summer artillery live fire training for cadets at West Point in 1986 and 1987. Versions: MINITSFO - Original version using a Digital Message Device (DMD), virtual map, and CGA graphics.
