What are you looking for exactly? The images you attached look to me like a
mapping of keyboard scan codes to the keys on an Amiga keyboard. The Amiga
keyboard has it's own microcontroller (MOS6509 IIRC) which sends the scan codes
over a serial connection to the Amiga.
The C128 keyboard is attached over a parallel connection to the CIA#1 on the
C128 main board. As can be seen in the
Commodore 128 Programmer's Reference Guide on page 642, the keyboard does
not send keycodes, but you need to read the bits of the CIA's data port and the
VIC2e. You could use the kernal's keyboard scan routine at $FF9F though, to
save you the hassle (see page 421 of the aforementioned book).
