Default Question about wiring rs232 cable for 882SIO board

I'm working onthe 2SIO board and trying to figure out how to wire the molex connector to the 25 DB female connector. I cannot figure out how to match up the pins. In the MITS manual I have, it is supposedly described on pages 28 and 29.

Page 28 describes the molex connector. It refers to pins 1, 2, 3, 4, 7, 8, and 10. I'm guessing that page 29 describes the 25 DB connector (it is not labeled). It refers to pins 2, 3, 4, 3, 8, 20, and 7

The problem is that page 28 shows 2 grounds while page 29 shows only 1, and page 29 shows a DTR on pin 20 and page 28 has no corresponding pin.

Any ideas?
Paul
