History

IBM had two distinct POWER- and PowerPC-based hardware lines since the early 1990s: * Servers running processors based on the IBM PowerPC-AS architecture in the AS/400 family (later known as iSeries, then System i) running OS/400 (later known as i5/OS, and now

IBM i IBM i (the ''i'' standing for ''integrated'') is an operating system developed by IBM for IBM Power Systems. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2 ...
