Yeah, this is an array of ZTex 1.15y FPGA boards, originally (2011?) designed to be bitcoin mining rigs, but never used as such at VHS, because they’d mine like, a couple cents per year or something. I think they’re currently off, or at least have no useful /expensive logic running now. Because they’re totally open source, they’re good learning platforms that have some beefy FPGAs inside. If the thing is plugged in and turned on, there’s an internal Raspberry Pi that is accessible through the network that can reprogram them. I think there’s something written in the wiki about it.
Happy to do whatever people want, here. They are technically on long-term loan from an ex-member, and my opinion is that they’re relatively good for education potential vs size they take up, but it all depends on the future of the server rack I guess.
