1161	 Compatibility Feature on the IBM System Model	 The second generation of stored-program computers of which IBM series was a part brought EDP into the mass market for the first time on a large scale. As this era unfolded rapid changes in technology led to rapid obsolescence of data processing equipment. Program written for a particular system required tedious conversion as incompatible new machines came into use. The IBM System has been designed with the conversion problem specifically in mind. One of the conversion aids available on the Model is the compatibility feature. This feature in conjunction with other aids permits a smooth and inexpensive transition to optimum use of the new system.
