Well Maurice Randall at Click Here Software bought out the rights to the C= version of Geos from CMD and he made what is essentially Geos 3.0, in what is called Wheels.
Unfortunately I would have to recomend not trying to purchase anything from Maurice right now.. He was always a stand up member of the 8bit C= community, but there is a preorder problem right now with him have taken money and not delivering products.. Not responding to emails any longer either...
Your best bet would be eBay.
