There are three places that the Disk Basic Code is patched. 

Patch 28 - $C0C6 of the Disk ROM Version 1.0. This points to the 
Copyrigght flash screen. that needs updating. This patch is only 
implemented if the disk ROM is version 1.0

Patch30 - $C0D9 is the patching of Disk basic V1.1 Copyright screen.

Patch29 - $C8B4 of the Disk basic Version 1.1 ROM and is 11 bytes long. 
This is the Keyboard Patch. It stores 11 NOPs.
