i5/OS V6R1: The TIMI, It Is A-Changing
August 20, 2007 Timothy Prickett Morgan
By their very nature, technology transitions are difficult. There were many brilliant things about the design of the System/38 and AS/400 minicomputers that are the ancestors of today’s System i platform, but perhaps the most important one is that IBM wove a technology-independent machine interface (TIMI) between the operating system and the underlying hardware. This has made changing the OS layer or the hardware layer a lot easier than is the case with other platforms. But sometimes, the hardware changes so much that even TIMI needs to change. Such is the case with the forthcoming i5/OS V6R1. And when TIMI |
