I don't know if you are aware of the Koruza open hardware project: http://www.koruza.net/specs/ http://www.koruza.net/scientific/ I'm not sure that is what you are looking for, but might be a good starting point. I can connect you to Luka Mustafa, who is the lead of this project - we have provided some grants to the project in its early days.
