I have one of the DE1 CycloneII device boards and at this point that family
(CycloneII) is a bit old.
If you can get it really cheap (<<$50) go for it, but the last Altera toolset
that supports CycloneII is v13.0sp1 (v15.0 is current).
I have moved most all my new experimentation on to the CycloneIV and CycloneV
If you plan to use a board going forward for some time, the newer CycloneV based
boards are a better choice:
In particular the DE0-CV has a lot of nice features for implementing a PDP-11
Or if you want to go light on the hardware design and lean more on embedded
software, the DE0-NANO-SOC board ($99):
The DE0-NANO CycloneIV board ($79) is also a good choice:
At this point I would stay away from CycloneIII or CycloneII boards (unless you
can get one very cheap) as the tech is older.
