hi kai, that schematic is the only one of the core there are however several schematics for other things i.e a schematic for adding NVRAM or EEPROM. I will see but i think i have added the first three chapters of the book to my homepage. Becaus there is somuch information in the book i wonder if you guys check out the index of the book and see anything you want just email me or post in the forum and i will scan those pages. this should also work for finding what we want to add to the schematic. the book is 280 pages!. As far as steve i dont have his email address. if you haven already seen my homepage.

later paul

ps i use hotmail messenger so it will tell me if you send an email while im on the computer.

later.......
