The 6800 is an 8-bit processor similar to the 6502, but not similar enough
be useful in Stella programming, where cycle counts and register usage must.
be tweaked exactly.  Here is a good
link to some online info about the 6502.  I wouldn't waste the time photo-
copying a book on the 6800 if it's the 6502 you're interested in.  Read the
book in the library to get a general drift of how .asm works, but study the
opcodes, register layouts, and code posted here to get a feel for the 6502.
Especially the indexing modes, which are *nothing* like the 6800.
