Edward Flottwell <edward@mudhoney.mitropa.com> wrote the following
about his kernel patch for allowing the kernel to work with an
adapted AS400 keyboard.
(In fact no kernel patch is required - the utility setkeycodes will do.
But the technical info below might be useful for somebody.)

Connecting and using a non standard IBM keyboard
by
Edward von Flottwell
edward@mudhoney.mitropa.com
If you would like to use an old IBM 122-key AS400 Terminal keyboard with Linux,
you should to do some small things:
1. Get your 'new' keyboard from a recycling company.
If you haven't done this already :-)
2. Solder a new 5pin DIN Connector instead of the RJ/??? Plug to the wire.
3. Patch the kernel and build an new one.
4. Load a new keymap and fit it to your needs.
I hope you managed the first step - so I'll continue with the second one:
Get a keyboard connector from your nearest electronic-shop, cut off the
original plug and you will hopefully find 4 colored wires: black, red,
yellow and white. Connect them in the following way with the DIN Plug:
Wire Signal DIN ___
Black +5V 4 / 3 \ Soldering
White GND 2 (2 4) View
Red Data 3 \1^5/
Yellow Clock 1
BUT BE VERY CAREFUL!!! Connecting the wrong signals can damage or blow up
your keyboard or your mainboard! The table above comes with NO warranty,
because I don't believe IBM always use the same type of cable :-}
You should open the keyboard and trace the wires to find the matching out.
And you should consult your mainboard for the keyboard-plug layout!
Now you're ready to switch on the computer... Some mainboard bioses will
produce a keyboard error. You can ignore this :-) BTW the F1 key is the
very left of the function-key group near the tabulator key.
O.K., now you can try to type something, e.g. LILO: linux :-)
You will find out that some keys are swapped, others are dead. To make all
of the keys work apply the kernel-patch to
/usr/src/linux/drivers/char/keyboard.c and comment the lines with
/* #define KBD_IS_FOCUS_9000 */
/* #define KBD_IS_IBM_AS400 */
out. Recompile and install the new kernel.
Now you need the last missing part: the keymap. At the end of this README
you will find an example for German users. How to make it fit to your
national keyboard is explained in the Keystroke-HOWTO. Most other questions
about keymaps, scancodes,... are explained there, too.
I would also suggest you read the manpages of showkey and loadkeys.
Don't forget to load the keymap every time you boot,
I prefer the rc.local shellscript doing this for me :-)
