Apollo Computer Inc has won a monster $100m extension to its existing OEM contract with Siemens AG that began with a $30m agreement over 18 months, signed in 1985. That was with Siemens’ Power Engineering & Aut-omation Division, and the new one adds Siemens’ Communication and Information Systems Division, which will now also offer Apollo workstation-based systems. In addition to its OEM relationship, Siemens has inst-alled more than 1,800 Apollo workstations used for in-house software development and computer-aided engineering at its facilities throughout Europe. The Siemens contract, Apollo’s largest ever, comes just six months after the 18-month $100m OEM pact with Mentor Graphics Corp.
