I had a visit from Jim and Tracy a few weeks ago in the shop. Jim has a site, cyclofiend.com. Go click around on the gallery if you want to see some eye candy in the form of 400 classic bicycle submissions from owners, which you can view by maker, if you like. Then, you can check out the collection of Nishiki and Univega bike photos on yojimg.net , which belongs to Jim G., another Bay Area cyclist.
Between both sites, you should be able to get more info on your old Nishiki, Univega, Bridgestone, Rivendell, and Ibis. (I drilled down through the links on a bunch of submitted classic bike gallery pages, and I ended up finding an article on my 1960s Legnano via ebyker.com.)
Wait until you get to work before you start clicking on these sites, or you are going to be late again.
Photo of the #400 submission to the cyclofiend gallery, a Heron Wayfarer, is lifted from the site.
Photo of the Univega happy cycling family is lifted from the yojimg.net 1983 Univega catalog directory.
