[Going from very ancient Unix manuals...] Regardless, there's a special processor built into your computer to take care of these items. Is there one for the NeXT's graphics? >Quit your whining. How much faster >would it be w/o DP? What purpose would it serve? It'd be faster, dude. What's the question again? Any real-time system will require every reasonable ounce of speed. It's one of the reasons why you don't page over a network. >The responsiveness(or lack of) is more than likely due to >paging. This has been covered before!! You're quite right, it has. Mind reminding us what it is that your pager keeps paging in and out of memory? No? Can you say "window system overhead?" or "Unix kernel overhead?" I knew you could. >What other systems have wysiwig displays? Your argument would be more compelling stated as: "What other systems have device independent graphics?" After all, any TV is a wysiwyg display. Truly, What You See is What You Get. Of course, it's the only thing you get, but that's my point, eh. In which case I could name several vendors selling several layers of device independent graphics. For the Mac and for the PC. You may argue their success in the technique, but... Even PostScript has its problems. See <>, for one. Remember Mike, you're talking to people who multi-task in 512k. The reasons for DP had better be *real* compelling. :) :) David Navas navas@cory.berkeley.edu 2.0 :: "You can't have your cake and eat it too." Also try c186br@holden, c260-ay@ara and c184-ap@torus
