I concur with K89's assessment. My guess would be a early 1980s, upper entry level or lower mid-range road sport model. It definitely no more modern than 1985 based on the decals. The road sport geometry and components indicate upper entry level, possibly mid-range. At this level, you typically didn't get bottle bosses, lever bosses and forged dropouts, until the 1980s. It's not higher end, by virtue of the brake cable stops and geometry. Knowing the seat post diameter would help to confirm the level.
