Yesterday eBay sent me some promotional email about the old Digilent NetFPGA Virtex-II Pro FPGA Development System

The NetFPGA is the low-cost re-configurable hardware platform optimized for high-speed networking. The NetFPGA includes all of the logic resources, memory, and Gigabit Ethernet interfaces necessary to build a complete switch, router, and/or security device. Because the entire datapath is implemented in hardware, the system can support back-to-back packets at full Gigabit line rates and has a processing latency measured in only a few clock cycles. 

It seems there is a multi-university research ecosystem hosted at netfpga dot org, with design examples and other resources.

Do you have access to a license for the EDA tools? If not, it is a brick.
Gaze not into the abyss, lest you become recognized as an abyss domain expert, and they expect you keep gazing into the damn thing.

Unfortunately no.

I would not go for that board. VII Pro is deprecated and it is not even supported by the latest ISE Tools. So you have to find an old version of ISE and probably a old version of operating system if that should run stable. I had to go through this procedure a couple of months ago to fix a new firmware to an old VPII Pro product.
So my advise is forget Virtex II Pro.

I second this. It was already old 10 years ago.
