Re: pinouts for numeric keypad //e

You need a female DB-15 to 11 pin female header.  If the female DB-15
is numbered like this:
__________________________________________
\                                        /
 \  8   7    6    5    4    3    2   1  /
  \  15   14   13   12   11   10   9   /
   \__________________________________/

And the 11 pin header is numbered like this:

_______________________________________
|                                     |
|  11  10  9  8  7  6  5  4  3  2  1  |
|_____________________________________|

Then:

DB-15     |     Header
__________|_____________

 12               11
 11               10
 10                9
  9                8
 NC                7
  7                6
  6                5
  5                4
  3                3
  2                2
  1                1


I don't think it can be adapted to the //c but I'm not certain.
Perhaps if you opened one of your //c's and looked for a connector
on the mother board but I really doubt you can use one of the ports.
