Hercules is an open source software implementation of the mainframe System/370 and ESA/390 architectures, in addition to the new 64-bit z/Architecture. Hercules runs under Linux, Windows (98, NT, 2000, and XP), Solaris, FreeBSD, Mac OS X (10.3 and later).
So why not turn your Raspberry Pi, the $35 ARM-based mini computer, into an emulated mainframe?
Load up your Rasberry Pi with the latest Debian image.
The Raspbian respository actually already has a compiled Hercules package. You can install with just a simple:
sudo apt-get install hercules x3270
This will install Hercules 3.07 from the Raspbian repository as well as a TN3270 called
x3270. In the mainframe world, you’ll need this type of emulator.
Now launch hercules and give it a configuration file:
That starts Hercules. Use the TN3270 emulator to access the Hercules console.
And you should get a screen like this:

TADA. Your Raspberry Pi thinks it’s a MAINFRAME.
