From: Sean Huxter on 8 Jan 2010 23:05 Mostly because all TVs only show you a portion of the picture, and if you're rendering pixels past that, you can never be sure your entire audience is seeing them. The border is a safe area that Commodore must have been pretty confident was sufficient to cover all TVs, because while some of us use the 1702 monitor (and others) which didn't have this problem as much, a heck of a lot of the users were using the RF converter, which could be on ANY kind of TV, which could indeed endanger seeing some of the rendered pixels. Pretty sound practice, actually. Better, of course, if you had a monitor that could stretch the image left/right and up/down to minimize the border. Sean.

From: Hg on 9 Jan 2010 01:33 Borders on the old 8-bits had a pleasing side effect (for me anyway) as it made the central screen area appear less blocky due to smaller pixels being mapped onto the screen.

There are indeed games displaying the current score and items as well as remaining lives on the bottom or top of the screen in the border area (I seem to recall "Ice Guys" being one of them). I can't recall games using the side border though, but that's to be expected, since important information really could get lost there due to TV overscan. > Was it easy? Relatively easy, if you knew the addresses and registers to read and use, not straightforward by any means though. ML -- ---------------------------------------------------------- "I don't know.
