do you know of a way to get GRX working or a graphical mode working under OSX? I am baffled as to how to begin.DOS is easier, but am working on a multi-arch/multi-platform program here. I'm looking for same routines as GRX or the old graph,and crt units provide.So far CRT unit doesn't redraw screen right.There is no GRX unit, only turtle graphix.
