In renewing its OEM contract with Arete Systems Corp, Unisys Corp is taking on two additional models from the San Jose, California Unix systems company. The new three year contract is valued at $150m and is for the Arete Systems models 825, 850 and 1200 which Unisys calls the 5000/85, 5000/95 and 5000/90 respectively. The 5000/90 is the only model that Unisys had sold previously. Unisys also announced recently that it had sold 2,500 of its Unix-based 5000 series last year throughout Europe and including the top-end 7000 series that it gets from Computer Consoles Inc, and its Xenix-based micros, total Unix sales for Europe come to 5,400 with the 7000 series brining in $1m in 1987. Unisys adds that its European sales were spread across the board, doing well in its traditional markets: UK, Sweden, France, Germany and the Netherlands. But countries such as Portugal, Spain and South Africa were absolute winners: Unisys claims 30% to 35% of the market for Unix systems in Portugal.
