Control Data Systems Inc is the latest struggling hardware manufacturer to sign up as a reseller for IBM Corp’s RS/6000 but so far it is restricting the agreement to Denmark, Norway and Sweden. Control Data will also supply installation, maintenance and support services. It justifies the move as proof that it is taking the independent system integration business seriously. IBM sells RS/6000s only through third parties in Denmark, where 60% of the top 500 companies are committed IBM sites. Control Data’s Denmark operation has been one of its most successful subsidiaries by concentrating on software and integration services. The deal may lead to others, although nothing has been signed yet in the UK or the US. IBM RS/6000s are already marketed by manufacturers Wang Laboratories Inc and Compagnie des Machines Bull SA.
