Ben- I'm forwarding your message to the neurorighter listserv, as I think it might be of use to the community
1) NeuroRighter is not under active development at this time, but this listserv, the google sites page <
https://sites.google.com/site/neurorighter/>, and the google code page <
https://code.google.com/p/neurorighter/> are all resources for support for NeuroRighter. We are currently moving NeuroRighter's code over to github (as google code is being retired)- there will be an announcement to this listserv once that is completed, but should be within a week or so.
2) for non-neurorighter hardware: NeuroRighter's software is primarily organized around using NI-DAQs for signal acquisition and generation. As such, generally speaking, it is possible to use NR with other amplifiers/analog equipment with some careful tinkering/tweaking of system parameters (as well as a thorough understanding of the NeuroRighter wiring system). However, if you are looking into equipment that includes an acquisition component (IE, an ADC), or does some multiplexing (such as Intan's chip), adapting NeuroRighter to your purposes will be more difficult and would require some coding. For an open-source alternative for Intan specifically, check out open-ephys:

hope that answers your questions!
