[Coco] Zork 1,2 and 3, and 6502 MS Basic are now open source

[Alex Evans]

Considering that there are other 6809 versions of MS BASIC beyond Color
BASIC (and it's extensions), I would suspect that MS does have a generic
6809 BASIC from which these are derived. That generic form should not be
encumbered by the rights of other entities.
