An interface is described which permits high‐speed wordwise data transfer between a Biomation 820 Transient Recorder and a MINC (LSI‐11/2) minicomputer. Using a DRV11‐B direct‐memory access card, up to 50 full 2 K records/s can be transferred to the MINC system; single word control data can also be passed from the computer to the Transient Recorder.
