There are also reports of a tussle inside IBM over how – and whether – to add OS/2 functionality to the RS/6000 – and talk at last week’s OS/2 Show in London confirmed this. The dilemma is whether to guest OS/2 under AIX or allow it to run as a separate operating system for efficiency’s sake. In addition, the same quarter claims that Microsoft Corp, which still has contractual rights to portable OS/2 on non-Intel machines, is toying with the idea of licensing it to Sony Microsystems which in turn has notions of putting it on the MIPS Computer Systems RISC chip the suggestion that OS/2 would be going onto the MIPS chip has been heard before, but without the Microsoft-Sony connection.
