Scarce, early pulse amplifier module built by Digital Equipment Corporation (DEC) of Maynard, Massachusetts, circa 1958, measuring 7Àù x 4.5Àù x 1.75Àù, marked "Pulse Amplifier 601" on the face. The module was designed to amplify and standardize pulses in width and amplitude and could drive sixteen pulse gates. This served as a 'building block' in an early modular digital computer package, used for testing and developing digital systems and components. It was marketed prior to the introduction of the first DEC computer, the PDP-1, in 1961. In fine condition, with some adhesive residue to the edges.
