"Ubiquitous Applications: Embedded Systems to Mainframe"
"To support a variety of platforms, Smalltalk uses a virtual machine approach to portability that allows applications to be easily migrated between platforms with little or no change to the code."
"… Smalltalk developers can work and deploy on Linux, Windows, AIX®, Sun Solaris, HP-UX, and OS/2®. You can also create applications to be deployed on the mainframe with VisualAge Smalltalk Server for OS/390 and z/OS."
