Or better: I bought 2 of them, in case I needed to destroy one to figure out connections etc. In an attempt to keep my wife happy, I settled on the $19 version. Various eBay vendors sell the same board for wildly differing prices: $1265, $185, and $19. Its real purpose is a gzip compression and decompression accelerator, a common operation in data centers that need to serve gzip compressed web pages. The AHA363 is listed as having an Arria GX FPGA, size unknown.
It'd be fantastic if it could be repurposed as a general FPGA PCIe accelerator board. FPGA development boards with PCIe support are never cheap, so I was particularly attracted to the Comtech AHA363PCIE0301G (AHA363). Most of them haven't really been comprehesively reverse engineered.
The FPGA board hack project on Hackaday lists a bunch of commercially available PCBs that have an FPGA in them. And while programming RTL is fun, I also love the whole process of reverse engineering, starting from a board that you don't know nothing about and step-by-step getting to the point where it becomes something useful. The Start of a Journey One can never have enough projects going in parallel.
