IBM will announce Summit in June 1990 with deliveries in the fourth quarter, believes Atlantic Computers Plc, which reckons the new machines will use the same technology as S and J 3090s, initially with 300 and 600 models and that it will be possible to upgrade 3090s to Summit; later in the life cycle, IBM will announce smaller and larger models, and there will be upgrades to replace the first generation Summit and to obsolete S and J technology; if Atlantic’s scenario is accurate, then there is a good case for continued investment in S and J models, and the company’s significant committment to 3090 CPUs would be vindicated.
