Do you have the pin-out of a MAX232 chip?

I two days ago bought a cable like the one Lee describes below. I have
used cables like this in the past to talk to RS-232 devices with no problems.
The cable I bought cost about $10. I bought it localy (Birmingham AL) so I don't
know where you can order it by mail :(
        I will be using the the cable to talk to a 17C42 via a MAX232.  I'm
 using
LabView on the Mac, so talking to the 17C42 should be a piece of cake. The 17C42
will be used to drive some LCD shutters in a vision science experiment.
