15.011 Does anyone have the pin-to-pin mapping that would allow me to construct a suitable internal cable for a IIe numeric keypad?

    You need a female Dsub-15 to 11 pin female header.  If the female Dsub-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


The header is as viewed on the motherboard.  The DB-15 is the female connector
that you would plug the keypad into.

• prev: 15.010 I have a Koala Pad with a 9-pin DIN female plug. I guess it's a C-64 model. Can I convert a C-64 Koala Pad to work on my Apple II?

• next: 15.012 Is there some cable or card which lets a II user connect two joysticks?
