I have seen an anomoly with my Radio Shack Color Computer, COCO,
with two video games that I have purchased.  It leads me to believe
that there is a non deterministic power-up condition in the
hardware that the software cannot correct.

For both Donkey King and Zaxxon,  great games by the way,
the system will often come up after the game load and execute
with colors reversed.  Donkey King comes up red/blue reversed,
I think, and Zaxxon definately comes up red/green reversed.
The instructions for Donkey King state that if this
condition occurs that the reset button is to be depressed
until the screen comes up red.  Zaxxon has no such instruction,
but if it comes up bad resetting does the trick.

Is there something in the SAM or the video controller which
makes this so?????
