Welcome to the forums. Your serial number format is consistent with a Taiwanese manufacturer, Hodaka, who was a known contractor for Bianchi bicycles.

Unfortunately, the serial number does not include information necessary to identify the bicycle model. To determine that, we'll need the brand and models of the major components (derailleurs, crankset, brakes) or, preferably, photographs.
