Hi BYS2,
I'm also interested in the new DE2-70. Please let us know your experience with it.
I downloaded the CD. The DE2-70 has some nice hardware enhancements, but the samples really stink. These DE boards are supposed to be educational. Samples should be fully commented. The samples provided though, are so poorly commented and (un)documented that you come to think it is on purpose. Let alone that many modules are encrypted ...
This was already true for the older DE boards. Now on the DE2-70 is, IMHO, worse. Many samples have been migrated from HDL to Nios. This make them almost useless as samples purposes.
On the other hand, it is difficult to complain too much. The hardware you get at this low price is unbeatable.
