Welcome, Brad, and nice find! +/- a year or so, this is probably your bike:

I have two Fuji's from the early '80's (S-12s, and a Berkeley), and am impressed with the overall componentry, build quality and ride. Yours is at the lower end (like the Berkeley), but still a very nice bike - especially for what you paid for it!
