[Coco] DMAPPS decoded part 2

[Boisy G. Pitre]

Nice work Willard. I have always wanted to know the details of the DeskMate stuff.

George Bethea really wants a Y2K compliant Deskmate 3.  I think he's on this list, but I see him every fest and he always asks me if I've done it.  Is this something you will be doing?
