IBM 'shows true colours' against open source Hercules mainframe emulator

Cliff Saran

Florian Mueller, founder of the NoSoftwarePatents campaign, has attacked IBM for stifling open source innovation.

Writing on his blog, Muellar said, "After years of pretending to be a friend of free and open source software (FOSS), IBM now shows its true colors. IBM breaks the number one taboo of the FOSS community and shamelessly uses its patents against a well-respected FOSS project, the TurboHercules mainframe emulator."

TurboHercules has filed an antitrust motion against IBM with EU regulators.

According to Muellar, the developers of TurboHercules asked IBM's permission to enable the emulator to run the z/OS mainframe operating system. IBM sent a letter to TurboHercules in March, warning the company that the emulator infringed more than 64 IBM patents.

Mueller said, "Hercules is simply seeking a way that its customers will be allowed to run IBM's z/OS mainframe operating system on Hercules. IBM generally does not allow its customers to run z/OS (hence also the application software those customers internally developed on top of it for trillions of dollars) on non-IBM hardware."
