RCA Spectra 70/15

The RCA Model 70/15 was a small-scale processor that could still support a variety of applications. Memory limitations and relatively low processing speed made its use as a stand-alone computer system somewhat impractical. The 70/15 was often used as a satellite processor for larger systems or used as an intelligent terminal for remote job entry. Typical applications of a satellite processor would include card-to-tape conversion, card/tape-to-printer report generation, tape-to-card punching, input pre-processing and verification, or tab-shop tasks like file sorting, merge, and data selection. Two memory configurations for the 70/15 were available: either 4,096 bytes or 8,192 bytes of core memory. The memory cycle time for a 70/15 was 2 microseconds per byte of information.
