It's hard to tell very much form a non-drive side photo but based on the serial number, in conjunction with features like a Unicrown fork, TIG welding and sloping top tube, it would appear to be a circa 1989/1990, Taiwanese manufactured model. It appears to be an entry level model on the basis of nutted axles and resin pedals. Pictures and/or makes and models of the major components (derailleurs, crankset and brakes) would help.
