Here is some information excerpted from "HP 3000 APPLICATION NOTE #71" about
terminal cables.  Is more info is needed, I can send the entire Application
Note, but this appears to be the relevant part.

Cables For 25 Pin RS-232 ADCC And ATP Ports

A. For HP 262X terminals with 50 pin connectors


                 13222N
                 ------
     50 pin MALE        25 pin MALE

         7  --------------  24
         9  --------------  22
        12  --------------   2
        13  --------------   4
        14  --------------  20
        40  --------------  23
        48  --------------   7


B. For HP 262X, 239X, 700/9X and PC's with 25 pin connectors and all RS-232
   printers, the minimum cable pinout configuration is:


                 13242Y
                 ------
     25 pin MALE        25 pin MALE

         1  --------------  1
         2  --------------  2
         3  --------------  3
         7  --------------  7

                          NOTE

The 40242Y cable is the RFI version of the 13242Y cable.


These cables have more pins than the minimum required pinout configuration
however, they can be used for system to peripheral links also.


                 13242N
                 ------
     25 pin MALE        25 pin MALE

         1  --------------  1
         2  --------------  2
         3  --------------  3
         4  --------------  4
         5  --------------  5
         6  --------------  6
         7  --------------  7
         8  --------------  8

        22  -------------- 22
        23  -------------- 23
        24  -------------- 24

                               NOTE

There are other cables similar to the 13242N. These cables are:
13242M, 40242C, 40242M, 92219G and 92219S.

Here is half an answer for you.  I have a 2624B as a console on my Series
37.  I can tell you my pinout on the Centronics side, but getting to the
back of my '37 to pull the cable is a _major_ ordeal, so I won't be able to
do that tonight......  :-(

My cable has 3 wires, Centronics 50 to classic ATP DB9:

    Wire:        CentronicsPin:    DB9 Pin:
    ==========================
    White        12                    ?
    Red           42                    ?
    Black        48                    ?

Unfortunately I didn't get a 262x Reference manual with my system, so I
don't know if it would have the full Centronics pinout.  I looked in both
the old Point-to-Point Comm manual as well as my older Communications
Handbook, and neither described the Centronics connector in detail....
