in this blog post there is a picture of the 2nd prototype of the MEGA65:
The prototype looks absolutely fantastic - just like the original!
But also the connectors on the backside look pretty much like the original (just click through the pics, it's more than just those 3 preview pics and on one of them you can clearly see the back with the connectors).
I wonder if this is a bit "fake" (to get some nice pictures) or if they all are really working? And if so, how are they connected to the Nexys board, or does this prototype already contain a custom board?
