I saw this bike on Craigslist http://honolulu.craigslist.org/oah/bik/733046244.html and don't really know much about the frame. However, I'm not super interested in the frame itself, but I was interested in the Shimano 600 group. I recently crashed my Bianchi, and so I am looking for some replacement parts. Good buy for the components? They look to be in pretty good shape...
