ABSTRACT:
A peripheral-controller (designated as a data-link-processor) manages data transfers between a main host computer and a magnetic tape peripheral unit. The peripheral-controller uses a common front end providing an instruction sequencing unit and a buffer memory to store data-in-transit in six blocks of 256 words each. A peripheral-dependent circuit unit of the peripheral-controller can provide automatic read or automatic write data transfers between the buffer memory and the magnetic tape peripheral unit without further attention from said instruction sequencing unit.
