> AS/400 (or whatever it is named today – the ISA that has never been implemented in the hardware anyway and has always been virtual and powered by POWER CPUs
To nitpick, the original AS/400 systems used a proprietary CPU called IMPI (Internal MicroProgrammed Interface), descended from the System/38. It was ported to the POWER series, or rather the RS64 in the early 90s.
The higher-level software, including parts of the OS, and all applications target a virtual machine.
