The Average Response Computer (sometimes referred to as the ARC-1) was not actually a computer (as implied by the name), but a digital transistor data recording/analysis device. It took a number of data samples, provided by an analog-to-digital converter, and summed and averaged them (hence the 'computer', since 'computing' is being done), to remove the noise. It was built at Lincoln Laboratory in 1958. Its importance was as a predecessor to the LINC (see the tale in the Clark history, below).
