I see, i actually thought it replaced both the host card and the
daughter card and didnt run an OS.
That after reading repo readmes and some of the issues i was linked to
before.
So it would still need an external daughter card. Still that is quite
interesting. if one could save on buying mesa cards why wouldnt one want
todo that. =)
The screen issue is a minor thing i dont think you reaaally would need a
full blown graphics display.. a alphanumeric display for basic network
and get it up and running
display would be nice tho - but that isnt hard to get running on those.
Nice compact solution anyway. =)

It's not acting as an addon board no?!
The DE0-Nano (and any of the other FPGA+SoC platforms supported in the
mksocfpga repository) function both as a control computer (with Linux
and machinekit running on the ARM hard core processors) and as a Mesa
open-source VHDL add-on card (ie: like a 5i24 or 5i25) running in the
FPGA fabric (with the full details depending on what you compile into
the FPGA). With a simple adapter board, it is possible to connect
Mesa 25 or 50 pin daughter cards to the FPGA as well (I have a 25-pin
adapter designed for the DE0-Nano).
Pretty much the only big missing piece for a full machine controller
is a decent graphics display, since none of the SoC+FPGA chips have
bulit-in graphics or GPUs, and those are complex enough it doesn't
really make sense to try and build a GPU with FPGA gates. You would
probably want to use a remote system or a tablet/touchscreen for the
display, or run a machine that doesn't require much in the way of a UI.
