Hi,  
  
I am trying to use Psychtoolbox to write visual stimuli that i will present to retina   
preparations placed on a Multielectrode Array from MEA systems. I will use Psychtoolbox   
from my G4 Powerbook hopefully, and am considering getting the Measurement   
computing USB-1208FS to send a TTL to the MCRack software run on a PC. The trigger   
channels accepted by MCRack, the MEA software, are taking both analog and digital   
inputs, through BNC connectors.   
  
Has anyone tried anything similar, and does it work ?
