As you said, the hardware setup itself is not hugely discussed, but that is because there is not much to discuss. The FT buffer is implement by a shared memory segment (i.e. some reserved address in memory that is accessible) and communication between computers takes place via a TCP socket. So, hardware requirements are memory and a network card ;) As long as your computers are not too ancient, there should also be no problem in terms of computational requirements. Our realtime computer is about 3 years old, our acquisition computer at least 4 (but I guess more in the range of 6-8 yrs). I am not working at the Donders anymore, so I cannot check the exact specs. Are you facing any particular problems?
