I've got one that was tested working several years ago (at least 5, I'd need to check it's tag) and carefully stored since then. But I can't test now. Williams PCB's are notorious for going bad just sitting on the shelf, so I'm guessing it's probably even odds (or worse) that it still works now. Interested in something like that?
Price? Tough call. $155 shipped?
I could test, but I don't know when I'll get a chance to get out to my buddy's house again, he's about a 90 minute drive one way (in good traffic).
