This is exactly what I'm talking about.  I have the source to some of those 
neat Bob Withers' games but not the assembler he used, so there seems to be 
a lot of work involved in translating and assembling the game.  However, 
making it an IDE project should simplify things.

Portal-9 comes with some sample 6809 code including a CoCo line drawing 
algorithm.  You still have to insert the pixel drawing subroutine(s) though.

What seems to be the problem?
