Looks like a 1980 Sportour mixte. Should be 19.5" frame. Chromoly frame w/ hi-ten fork so it's one of the nicer mixte frames they made that year. 27" Araya alloy rims on quick release shimano hubs. Altus derailleurs + shifters, sakae cotterless 40/52 crank. Catalog says it weighs in at 26lb that year.

I had rebuilt an 82 viva sport mixte for my girlfriend with new upright bars, cork grips, new tires, and a complete overhaul. That had a cromoly frame too, kind of hard to find in a mixte. She loved it but we ended up selling it to a friend for $150 when we moved.

I'm not in Portland, but southern california has a pretty hot bike market too, and 220 seems kind of high for that bike in that condition.
