The developer of Hercules, the open source mainframe emulator, has formed a company called TurboHercules to support the product.
Hercules is an open source software implementation of the IBM mainframe architecture, which has been developed from open source contributions. The product is able to run current versions of IBM's 64-bit operating systems, including z/OS, z/VM and z/VSE, as well as its older 31-bit and 24-bit operating systems.
While IBM's licensing forbids moving applications and workloads from the mainframe, TurboHercules said the product's niche is to focus on ancillary workloads such as mainframe education, training, demonstrations, pre- and post-processing, data preparation, archiving, development and testing.
Under IBM's licensing, Hercules could be used to provide emergency back-up if a mainframe site fails.
