We’re starting to get the impression that the source code tree on which Hewlett-Packard Co is basing its 64-bit code is UnixWare, which would explain why the company is so very reluctant to say so, suggests Unigram.X, our sister publication. It doesn’t want to make its installed base nervous. But users aren’t the only ones wriggling around uncomfortably in their chairs these days because Hewlett’s OEM customers say that despite an agreement with Santa Cruz Operation Inc not to seek out co-development helpers past folks like NEC Corp and Hitachi Ltd that are covered by pre-existing arrangements, Hewlett is still sending feelers out, making those who’s shoulders are tapped feel a bit anxious. The buy-in, as we have said, is said to be $55m to $60m over three years. NEC is apparently in, but Hitachi seems to be having second thoughts over the return on investment. We have to see what, say, Fujitsu Ltd does. The fact that Hewlett-Packard really is in the driving seat is also starting to sink in.
