    Yep, it is a small world! I use two 6 switch DIPs to mod a VSSB. The jumpers are normally numbered 1 thru 7 starting in the middle. Since the number 1 jumpers are not changed, I skip them and install one of the DIPs upside down to keep the numbering going from the inside out. I hope that makes sense, sometimes things sound better in my head. Instructions are included which show an example of the switches set properly. No problem on the connector, I try to give forum members a better value for their purchase when I can. I also upgraded it to Priority Mail.

    Yeah, thanks Brian. That's one document I don't think I've seen all of before.
