[Coco] Coco Digest, Vol 126, Issue 52

Hmm - must've missed that part. That's too bad.

You mentioned Barden's book, and I am sure I have a copy somewhere (?) - 
but does it go into the specifics of how to use the GIME, etc in the CoCo 3?

Because that is what I am after. 6809 assembler can't be any more 
difficult than any other assembler I have used and abused in the past; 
I'm not saying I am an expert or anything, but I do have such 
experience. Many years ago, I wrote a graphics library for QBASIC 
1.1/QuickBASIC 4.5 called "The Blast! Library" - all the main routines 
were done in 80x86 assembler.

The thing is, there seems to be so little out there about how to 
properly use the GIME, etc to do things like scrolling, memory copying, 
etc - as well as setting up and using the various CoCo 3 graphics 
screens and such. What little there is, is scattered across a variety of 
articles.

I would love to see a real tutorial on how to write a simple CoCo 3 
game; heck, if someone wrote a tutorial on how to make a game of pong or 
space invaders using 6809 assembler, on the CoCo 3 screens, that would 
likely be more than enough.

Hint, hint...anybody? ;)
