Description: System/370, ESA/390 and z/Architecture Emulator
Hercules is an open source software implementation of the mainframe System/370
and ESA/390 architectures, in addition to the new 64-bit z/Architecure.
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. (Note:
Not all 370 and 390 features have been implemented in Hercules. See
the manual for a list of particulars. Also, certain non-standard
models, 360/20s, and the 360/67 virtual memory mode are not emulated.)
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 write
the operating system or standalone program yourself, unless you can manage to
obtain a license from IBM to run one of their operating systems on your PC,
use IBM programs and operating systems which have been placed in the public
domain, or use a free software operating system such as Linux.
Virtual networking can be accomplished using the TUN/TAP driver in
2.2 and 2.4 kernels. For older kernels, try the vmnet package.
