Tango-Schematic (ver 1.50) Abandonware Accel Technologies, Inc., Tango-Schematic is an electronic schematic drawing program. It is similar to the popular "Orcad schematic capture". Tango-Schematic drawings can be used by the "Tango-PCB Plus" printed circuit board layout software (also available on this Gopher server). NOTE: Software requires the "TANGOCRK" TSR to be running for it to function (pre-configured with "run.bat").
