DEC PDP-8 Emulation on an FPGA DE0-Nano

I have duplicated the work of Tom Hunter on the Facebook DEC PDP-8 Group.
Tom ported an Opencores PDP-8 emulation to the Altera DE0-Nano board and shared his code with the group.
Same board , same code, but my experience with the software tools is limited so I was surprised when it worked!

The processor is running a short demo program fixed in the FPGA code - the blinking lights show the top 7 digits of a simple counter.
