They may be too antique to find at a PC recycling type of place but it would be worth looking. I can't imagine it being more than a few bucks and by the time it's shipped from one of us, unless it's local or given to you for free, you will probably save money with the recycling place.
I can call my grandfather (perpetual pac-rat) and see if he has some. If he does I'd probably only charge shipping from Seattle but I wouldn't be able to guarantee a quick process. If I had time to pick it up this weekend I could send it from work on Monday, but that's if he has it and if I make it over to his place this weekend. Try local and if that fails and nobody else has a more promising offer PM me later this week.
