Landover BBS - Commodore 128 & PET - since 1987

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).

Can you please write a simple test program, that measures the time it takes to count some loops, fill the screen or similar and post it with the values from the real machine to the vice bugtracker?

Anybody programming already?

If you have list of tokens/keywords, you could add them to petcat yourself. The source is free. Even more, some people would thank you very much :)

You could use petcat, which is included in VICE.

Call it from a shell with
petcat -o destination_filename.bas source_filename

Voilá.
