12 volt revy x-board question?

[tombraider68]

By looking at the board of a Revy, is there anyway to tell whether or not it is an X-board? I bought a revy from someone who did not know if it came with the x-board and now that I am trying to sell it I need to know this. Also whats the difference in balls per second feed between an xb and a non-xb revy?
Your help would be greatly appreciated.

open the battery compartment. at the bottom of the battery well, "x-board" is marked on xboard version. if there is no writing it is not xboard.

if it came installed with the xboard, it will say so on the hopper. otherwise, follow tombraider's tips.
