RevEng Reverse-Engineering Tool For Recreating Schematics

ABI's RevEng System is a remarkable reverse-engineering hardware tool for creating professional quality circuit schematic diagrams from a sample PCB that lacks documentation. The RevEng System consists of a PC-controlled continuity-detecting hardware system, RevWin control software, and EdWin, a fully featured CAD package. RevEng ‘learns’ the connectivity of the sample circuit, producing a netlist of the components and connections for importing into EdWin software, resulting in professional quality circuit diagrams.  See http://www.saelig.com/MFR00134/TSTEQPCB009.htm
