I looked around and didn't see this posted. I was clicking around
http://home.earthlink.net/~icls
which is John Ulaszek's wonderful site on SFIC (from which you can order some great SFIC tools by the way).
I found this technical manual for the BEST Ultra Security / Xperinetix Core:
http://home.earthlink.net/~icls/Ultra%2 ... Ver1.2.pdf
This is basically a BEST SFIC reference combined with a catalog of ICLS products. It really is a great reference. The Ultra Security core is not really any different than standard cores it seems.
Probably no new information for most of you guys, but it has great diagrams and reference info as I said.
