[Coco] Want William Barden's 'Assembly Language on the Color Computer III'

[Brian]

Hi Fellow Coconuts,

I want to purchase a copy of this book, Or if you can't get this anymore, Does anyone know how to contact Mr Barden, And ask for permission to scan the book into PDF format, So others can download it.
This book would be perfect to learn a bit more of assembly programming for the coco 3.

Viva Le Coco
