Thanks for sharing.
Just a thought, but do I see a Cyclone II? It's a 14-year old device...
I don't really know how much longer Intel is willing to maintain this series, now that it's Intel.
Any reason you didn't select something a tad more recent? I don't know the Altera line well, but something that seems roughly equivalent but already significantly more recent at an equivalent price would be the EP4CE6E22C8LN (Cyclone IV). The Cyclone V seems more expensive. Maybe the new MAX10, but it would probably be a bit more expensive too although I don't know how they would compare to a Cyclone II.
Or maybe it's part of the retro thing, in which case don't mind me.
