pcb (software)
PCB is an open source software suite for electronic design automation (EDA) - for printed circuit boards (PCB) layout.
History
PCB was first written by Thomas Nau for an Atari ST in 1990 and ported to UNIX and X11 in 1994. Initially PCB was not intended to be a professional layout system but as a tool for individuals to do small-scale development of hardware.
Harry Eaton took over pcb development beginning with Release 1.5, although he contributed some code beginning with Release 1.4.3
