The SoftDevLabs version of Hercules 4.x (Hyperion)
Hercules is an open source software implementation of the mainframe System/370 and ESA/390 architectures, in addition to the latest 64-bit z/Architecture. Hercules runs under Linux, Windows, Solaris, FreeBSD, and Mac OS X.
Hercules is OSI Certified Open Source Software licensed under the terms of the Q Public Licence.
This version of Hercules 4.x Hyperion is a SoftDevLabs maintained version of the Hercules emulator containing fixes made by myself and others for bugs that may still exist in the original hercules-390 version of Hercules 4.0 Hyperion, as well as enhancements and improvements to the overall functionality above and beyond what is provided by the hercules-390 version of Hercules.
Hercules was created by Roger Bowler.
Jay Maynard "the Tron Guy" was the maintainer from 2000 to 2012.
Jan Jaeger designed and implemented many of the advanced features of Hercules, including dynamic reconfiguration, integrated console, interpretive execution and z/Architecture support.
Until shortly after the Turbo-Hercules debacle, a dedicated crew of programmers was constantly at work implementing new features and fixing bugs. It is questionable whether the same is true today. Thus the reason for the existence of this SoftDevLabs version of Hercules 4.x Hyperion: to try and keep the Hercules project alive and active. (Sadly, there's not a lot of activity these days with the original version of Hercules. The SoftDevLabs version of Hercules 4.a Hyperion however (i.e. this version), seems to be the only 'active' version of the Hercules emulator in existence.)
