This means that your PC can emulate an IBM mainframe processor. The mainframe can range from a 360 to a z900 - running in "System/370" mode, "ESA/390" mode, or "z/Architecture" mode. Hercules executes S/370, ESA/390, and z/Architecture instructions and channel programs. It emulates mainframe I/O devices by using PC devices. For example, 3390 DASD devices are emulated by large files on your hard disk, and local 3270 screens are emulated by tn3270 sessions.
Hercules implements only the raw S/370, ESA/390, and z/Architecture instruction set; it does not provide any operating system facilities. This means that you need to provide an operating system or standalone program which Hercules can load from an emulated disk or tape device. You will have to use a free software operating system such as Linux, write the operating system or standalone program yourself, obtain a license from IBM to run one of their operating systems on your PC, or use IBM programs and operating systems which have been placed in the public domain.
Virtual networking can be accomplished using the TUN/TAP driver in host Linux kernel.
hercules for Debian ------------------- If you want to use virtual networking without running Hercules as root, you will want to add a statoverride for /usr/bin/hercifc: dpkg-statoverride --add --update root <trusted group> 04750 /usr/bin/hercifc -- Matt Zimmerman <email@example.com>, Thu, 26 Apr 2001 01:46:24 -0400 Installing Debian on an emulated S/390 system ---------------------------------- more»
