[Coco] 6X09 Assembly Newbies.

[Steve Ostrom]

One good example is the one I showed my son this past summer.  Use a 
small ML program to fill up the text screen.  Compare the speed with a 
BASIC program that does the same thing.  It really blew him away, and we 
just hand assembled the program and executed it.  Very simple but 
impressive.
