Lugged steel Yokota, not a super high end bike back in the day (they are not Japanese, they were made in Taiwan). Made early to mid 1990s, they stopped making bikes in about 1996. I'd guess about $600 when it was new. The 7-speed Ultegra is probably original.
Take it down to Pearl Street and find the skinniest dude about 5'6" with the tightest jeans, he'll probably give you $100 for it just so his fixie is not a Miyata or Raleigh.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
