Dan, I think you need to post your question in the California section. Unless an Oregon lawyer has taken and passed the bar in the California, they will not be able to help you. This might be the sort of thing you can take care of over the phone with a California lawyer if you can pull them away from their ipad and iced mocha-latte frappuccino. Alternatively, you could just never go to California again. I imagine if they were planning to extradite you it would have happened by 1992 or so.
You may be an excellent candidate for what is called a "Serna motion," which helps people get rid of ancient cases like yours. I have written dozens of Serna motions and I would be happy to help you. I am licensed to practice in both California and Oregon. Please give my firm a call at (503) 592-0606.
