I just bought a NeXTcube to run an auditory perception laboratory and I'm trying to determine the best way to set up multiple (4 is what I have in mind) response stations that will allow subjects to enter their responses. I usually use same/different or two-alternative forced choice procedures so I don't need full keyboards or video displays for the subjects. One suggestion I got was to hook up terminals to the serial ports. This would work, but requires adding serial ports to get four subject stations. I would prefer a more elegant solution where on routine is monitoring four response boxes that are connected to one port (perhaps daisy-chained off the SCSI port?). If anyone has worked out a solution to this problem or thinks they know how it could be done, I would very much like to hear about it. Thanks, Gary Gary R.

You could wire each victimswitch in parallel to a unique keyswitch on a keyboard. Don't use one of the priceless old ones. Trade someone for 2 of the new ones. On second thot, sacrifice an old dumb terminal attached to a serial port. *CAUTION*. I am a software person and have done none of these things. I do have an old keyboard. I'm keeping it. ;-)
