Peripheral Interchange Program
Peripheral Interchange Program (PIP) was a utility to transfer files on and between devices on Digital Equipment Corporation's computers. It was first implemented on the PDP-6 architecture by Harrison "Dit" Morse early in the 1960s. It was subsequently implemented for DEC's operating systems for PDP-10, PDP-11, and PDP-8 architectures. In the 1970s and 1980s Digital Research,Inc. implemented PIP on CP/M and MP/M.
