Prime Computer Inc’s Computervision is spreading its favours around and has new OEM agreements for Sparcsystems with both Sun Microsystems Inc itself and with Solbourne Computer Inc for its Cadds and Medusa computer-aided design applications. There is no value on the 18-month, renewable Solbourne agreement, but Computervision is in for $200m a year with Sun, up from $100m a year under the contract it supersedes.
