So I got this for $20 from a local ad. Rusted chain, bad tires, torn saddle, shifters don't work. The frame is in good shape. I like vintage diamondbacks so for $20 why not? I re-packed wheel bearings, bottom bracket, new chain, saddle, grips, cassette, brake pads, and new rear derailleur. The frame is actually very light and it's just a good looking bike overall. I believe this is one of the early stab using 700c wheels on a mountain bike. I still need to install a front and rear racks then I will be done with it.
