EEG testing:
Maybe you could testing the EEG
a) before the electrodes (partial)
b) after the electrodes (full)
for a) you can use a digital signal file of EEG through a simple DAC (http://www.hut.fi/Misc/Electronics/circuits/r2r.html ) connected to a parallel port (Printer) .
a1) make a simple sine function file
a2) use a EEG file from Internet ( Paul Conlon <EEGcd_at_S...> has offered to send 2 CDs with all the datasets from the below article to anyone who asks. see http://www.ingber.com/smni97_eeg_data.html )
obs: adjust the output of DAC to the expected level of the RS232EEG input .

At the moment I don't have any EEG probes.
What is the fastest way to get proper probes for testing????
Now I'm drawing analog PCB and soon post it for comments.
And I want to build Digital part before make the PCB.
