trigger eye tracker and TMS

[David McFarlane]

Sara,

I don't see any way to do this other than to get out the soldering 
iron and build a custom cable to spit the signals from your 
computer's I/O port (e.g., parallel port) and send some bits to one 
instrument, and other bits to the other instrument.  Then you can 
decide which bits to designate for which instrument, and from there 
it is merely a matter of writing your program to measure & control 
those bits as desired.  No big deal.
