Digital Systems Development SA denied rumours of a deal with Microsoft Corp to distribute Windows NT and reaffirmed its commitment to Unix. In fact managing director Almerino Furlan warned Microsoft that it could go the same way as IBM Corp because, like Big Blue, it is trying to spread itself too thin. He added The way we see the client-server and distributed data processing market leads us to believe that Unix has a clear advantage over any other operating system. Sales and marketing manager Mariano Romero affirmed that the Madrid company would continue to sell communications software and services, which enable the integration of multivendor host computers. According to Furlan, it plans to focus on systems integration, providing turnkey systems to financial institutions and government – the two markets, which have shown most interest in Unix. Digital Systems is also expanding its end-user training courses to cover Informix Corp, Santa Cruz Operation Inc and Uniplex Ltd environments.
