[Coco] Reading keyboard input without basic

[Dave Philipsen]

I agree.  It would just be good practice to do so even if for just the 
CoCo because it is possible that someone out there has some sort of 
custom ROM.  But as long as they've followed the rules for the vectors 
to the ROM routines then the code will always work as JSR [$A000]  while 
it may not work on a custom ROM with the direct JSR.
