[En-Nut-Discussion] Building Medianut and/or LCD-display add-on

[janne.jarvinen at pp8.inet.fi]

I am a little bit confused about connector between add-on boards and Ethernut main board.
What does this mean:
"Two sides of the the board may be plugged into the Ethernut expansion connector. This offers the possibility to install both boards either in the sandwich way(x1+x2) or side by side(x3+x4)"

Cannot find anything related to X1-X4 in Ethernut documentations. Only one simple 64pin header incl.Ports,addr,data etc.
Cannot either understand what means "both boards" ?

So for some way, both Medianut and LCD boards can be conencted at the same way ?

Does somebody have pictures of ready build bords ?

Regards,
