For background to sibling comments - AS/400 aka "System i" was historically a separate line of processors, but is now POWER running a software translation layer. https://en.wikipedia.org/wiki/IBM_i#TIMI https://en.wikipedia.org/wiki/IBM_i#TIMI To illustrate why the AS/400 had its market niche, the Cali Cartel had a very successful installation of an AS/400. Apparently they used it to do both "business analytics" and back-office tasks. https://www.vice.com/en/article/the-cartel-supercomputer-of-1994/ https://www.vice.com/en/article/the-cartel-supercomputer-of-...

> For background to sibling comments - AS/400 aka "System i" was historically a separate line of processors, but is now POWER running a software translation layer. The software translation layer has been a feature of the platform dating back to the System/38 days, and was specifically intended to allow the CPU architecture to change without breaking software compatibility. IBM i also has the "PASE" layer, which is a binary compatibility layer for AIX. Those applications do not use the translation layer.
