There were numerous discussions about the need for more implementations of the Forth kernels. Each company had a good one. It was time to forget about implementing Forth and get on with the work of Forth applications. It is interesting that most of the Forth Vendors could not make a business on sale of their implementations alone. As far as I know they all provided custom services for specific applications.
Vendors often tailor their kernels for each application.
The early conflicts in goals among Forth users stimulated a wide variety of directions. The differences were always well discussed at fig meetings and conferences. The discussions were lively and comments were at times a little on the sharp side. This was the time of the heyday of Forth interest. We had a Byte issue which featured Forth.
