I really don't see how any useful general purpose dynamic graphics can be presented within a browser without reinventing and then reimplementing a ton of what X-Windows already provides. Of course, maybe I'm looking at this the wrong way, so please outline with some details how the current functionality provided by what currently exists in just the display library would work. The original display functionality had various interfaces to X11 and Win32 for host display. I added glue behind that to hook it into the existing simh video functionality. Let's see what a reinvented model looks like which is transported and presented within a web browser. Once we understand what that means and looks like, we can figure out how to fit it into the simulator framework. - Mark _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
