fired up the ohm meter this morning and my results confirm fowlerm's.
my board is also labeled rs-talos rev nc3.
note that the master and user controllers are not oriented the same way on the board and that the c1out, (pin 18), is 90 degrees away orientation-wise, from tx2, (pin 38).
to test i plugged a straight through 6 pin cable into the programming port and a jack with wires hanging loose, then connected my ohm meter to the various wires at one end and to pins on the chips at the other. the wire colors i got are the same as reported by fowlerm.
furthermore, with the board powered up i read 4.9 volts on rb0, (green). this pin has an internal pullup, so i assume that that's appropriate, and that connecting a switch between rb0 and ground will generate and interrupt on the master controller.
haven't managed to get a cable working but, hey, i'm in way over my head.
good luck.

2- RJ3 (master)
3- GND

5- +5v
6- can't find where it traces to yet
My VEX board has this printed on it:
RS-TALOS
REV NC3
This is on the serial port and not the RX1 or RX2 ports.
Thanks,
