Code is available for download at my sourceforge project page.
You need the QT libraries version 3 or higher to run resistor. If you have KDE 3 you should be all set. Otherwise you can download the code from Trolltech and build the library. I've uploaded a Linux binary which works on RedHat 7.2 and a Windows binary. You can download both on the sourceforge project page. The Windows version requires the Microsoft C and C++ runtime libraries (msvcp70.dll and MSVCR70.DLL). These files can be downloaded from the sourceforge page in the DLLs.zip file if desired. Alternativley the Windows_complete_install.zip file contains everything necessary for a Windows installation (the main executable, the C/C++ runtime libraries and the QT libraries). If you're not sure what to download and you have a Windows machine download Windows_complete_install.zip.
