Well I can't answer all your questions without further consideration that my customers won't let me have the time for right now. BUT as to whether a card is 3.3v SIGNALLING or 5v (not power voltage), maybe this will help: http://www.soundonsound.com/sos/dec04/articles/pcnotes.htm It doesn't show a 3.3v only card. Just a 5v and a universal one but you get the idea. BTW you can tell that aeronautical electronics people didn't design the edge connectors on PCI cards: It is easy to fit a 3.3v card in a 5v only socket by putting it in backwards (or vice versa). Neither usually survives. It is hard to do in a PC case but when you have to remove the "plank" to use the card in an embedded system it is simple for the unwary to reverse the card. HTH, have to run. Rod/ >From the land "down under": Australia.
