 IBM developed a Token Ring card for the PC in time for its launch
 based on this intent, long before the Color Graphics Adapters were
 available, about six months after launch, and the CGAs were only
 produced in response to the completely unanticipated demand for the
 PC.
 
I didn't think IBM introduced token ring until 1985 or so...
