| The 70/15 was often used as a satellite processor for larger systems or used as an intelligent [[Computer terminal|terminal]] for remote job entry. Typical applications of a satellite processor would include [[Analog-to-digital converter|card-to-tape conversion]], card/tape-to-printer report generation, tape-to-[[Punched card|card punching]], input pre-processing and verification, or tab-shop tasks like file [[sorting]], [[Merge algorithm|merge]], and data selection. Software for this model did not include an [[operating system]]—the ''RCA 70/15 Programming System'' consisted of an "Assembly System, Loader Routines, [[IOCS|Input-Output Control]], Test Routines, [[Utility software|Utility Routines]], Communication Control, System Maintenance Routines, [[IBM RPG|Report Program Generator]], and Sort/Merge." Sort/Merge required a system with 8 KB of memory. The remainder could run in 4 KB. Programs could be run from punched cards or magnetic tape.<ref name=SIM />{{rp|pp.43–44}} | The 70/15 was often used as a satellite processor for larger systems or used as an intelligent [[Computer terminal|terminal]] for remote job entry.

| It was used by the Oklahoma State-Wide Computer Science System, starting in 1966, to connect remote RCA 301 computers in 8 cities to host Vocational-Technical Education in computer science, which was the first state-sponsored program set up exclusively to train data processing personnel. The students were learning the fundamentals of programming and system operation with "hands-on" experience. | It was used by the Oklahoma State-Wide Computer Science System, starting in 1966, to connect remote RCA 301 computers in 8 cities to host Vocational-Technical Education in computer science, which was the first state-sponsored program set up exclusively to train data processing personnel.
