[Coco] Having fun with hacking HDB-DOS

Hi Juan!
Please disregard the previous message.  I must have had a little brain fog!
I do remember that this is for the Coco 1 & 2.  Have you written any
documentation for you upgrades yet?

Hi Juan!
I thought you were adding to the commands in HDB-DOS.  Which ones have you

All CoCo 3 tokens are recognized, but of course most don't do anything.
LOCATE, WIDTH and BUTTON work. Try WIDTH 51 and WIDTH 64.
