"The Atari & Commodore machines can operate at many different screen resolutions and would require a multisync monitor for optimum flexibility. Also, the Commodore Amiga 1200's maximum resolutions are interlaced(i). It's maximum non-interlaced resolution is 640x480. Both the Atari Falcon & Commodore Amiga 1200 will also overscan, giving them more resolution in that mode and making them suitable for Desk Top Video (DTV). The Apple Performa would require an analog VGA type monitor. With additional Video Ram, the Performa can display up to 32,000 colors maximum."
Maximum non-interlaced resoulution for the A1200 is 1280 x 256 or 1472 x 290 (with overscan) not 640 x 480. Oh, and wasn't the apple a bag of %&$#?@!%&$#?@!%&$#?@!%&$#?@!e.
