[Elecraft] P3 SVGA board question?

[Sam Morgan]

I may have a chance to buy a P3 SVGA Board. It was bought shortly after they 
were released, but never installed. I don't know if it has a serial number or 
exactly when it was bought.

My question is.....
Has there been only one version of the board sold?
In other words, are there early boards that would need any parts upgrades,
or are all P3 SVGA boards alike and only the firmware has been updated?

TIA
