Joe - I think I might have complete docs, and luckily for you I was planning on doing some cleaning and re-organizing in my basement this weekend. Let me look. Another possibility is to email Jeff Bachiochi [Jeff.Bachiochi(a)circuitcellar.com] with any specific questions. You can tell him I told you to contact him - if he's in a good mood, he won't hold that against you <g>. Bob Stek Saver of Lost Sols
