Siemens Nixdorf Informationssysteme AG and its Pyramid Technology Corp subsidiary have rejected NEC Corp’s Golden Gate route to 64- bits and 3DA Unix, saying they don’t believe 64-bit presents enough of an opportunity to move its Reliant Unix customers on to Unix SVR4.2MP and recover a return on the investment before a second move will be required to implement a further next- generation Unix of some kind. The two companies also don’t believe that NEC’s Tower will support the kind of scaling it requires. HP and SCO have not made it clear who has ownership of what relationships, they say, and while they sincerely believe SCO is trying to maintain a level playing field, they also hold the view that Hewlett-Packard clearly wants its PA partners to have a more level playing field.
