Hardware Description

The RCA Model 70/25 was a small-to-medium scale computer system that supported a wider variety of applications, including use as a free standing system. In large installations, the 70/25 might also be used as a subsystem in a multi-processor complex. High throughput was facilitated by the use of fast memory and multiple simultaneous input/output streams. Equipped with selector channels and a multiplexer channel, the 70/25 could concurrently operate eight low-speed devices in addition to eight high-speed devices.Memory capacities for the 70/25 ranged from a minimum of 16,384 bytes to a maximum of 65,536 bytes. The memory cycle time was 1.5 microseconds to access one 8 bit byte.
