E-prime 2.0 & SRBox & ERP

[Sibel Ozer]

Thank you Jan and Meltem.
Jan, actually, we have money but not so much:)I just search for possible
devices. What do you use as the EEG system. I looked sending triggers a
bit. I think sending TTL signals to an external device need parallel port
connection if I am not mistaken.

best,
Sibel
