We're quite bad at documentation (sorry!) still. It appears you haven't 
stumbled upon the more recent bits on our Wiki.

We used the Novena, Spartan FPGA and that Noise board about a year ago. Since 
then, we've manufactured our own Alpha board with an ARM CPU and a Xilinx 
Artix 7 FPGA on it, and also the noise circuitry. If you want to get involved 
in development I suggest you start with acquiring an Alpha board.

There was a workshop in Berlin a month ago. I would recommend you read the 
presentation slides at https://wiki.cryptech.is/wiki/BerlinWorkshop to get up-
to-date information about how things are now. Also, look at the various 
"Alpha" pages on the wiki to see what hardware is there, how it is connected
