Hebe is a KDE 4.4 front-end GUI for the Hercules z/Arch emulator. It was designed to have a modern look, like the VirtualBox interface; there are no dials. Hebe provides two consoles, one for Hercules and one for the SCP (system control program), also known as the operating system. Input is automatically routed to the correct receiver. You can start as many instances of Hercules as your hardware can support. Hebe works best with Hercules 3.0.7.
