The serial number indicates that the subject bicycle was manufactured in Japan during February 1985. The 1985 Bianchi Nuovo Alloro was manufactured in Italy, so we can rule that out. The highest Japanese manufactured model during the time was the mid-range Limited but it came with Shimano New 600EX, so it would not appear to that either. You don't mention any model name for the Shimano derailleurs. Given the era, that sounds like possibly the nondescript Z-series, which was used on entry models like the Strada, Sport and Classica.
