[Coco] print samples

[Aaron Wolfe]

I've put a couple samples of the output from the printing tool I'm
working on here:  http://aaronwolfe.com/coco/fx80img/

If anyone has feedback on the appearance, I'm trying to get it looking
"real" :)  Next up is graphics mode which I think will be more
sensitive to proper pin spacing and such than text mode is.
