I am more of a lurker on this mailing list but I thought I'd chime in
on this one due to the fact that I have a collection of books from my
'more active' CoCo days ... the ML programming ones include ....
* - TRS-80 colour computer assembly language programming by William
* - The MC6809 Cookbook by Carl D. Warren
* - Machine language programming from the ground up by Hubert S. Howe
* - Assembly language graphics for the TRS-80 color computer by Don &
* - Programming the 6809 by Rodnay Zaks & William Labiak.
* - MC6809-MC6809E microprocessor programming manual by Motorola
I'm pretty sure 'all' of these books predate the CoCo3 but they're a
great starting point.
I am offering any/all of these books free (except for postage) to
anyone who can make use of them.
I am located in Melbourne, Victoria, Australia & the weight of the
books listed is about 2.5Kg
Obviously I would prefer pickup but I seriously doubt that is likely

Australia isn't "down under", it's "off to one side"!
