cards, a separate VGA card was required. This increased the cost of ownership as one had to purchase two rather than one expansion card for graphics. A temporary solution was presented with the ATI Graphics Ultra/Vantage cards, which combined an ATI 8514 Ultra and VGA Wonder+ into a single card (though using discrete ICs). The Mach32 chip was the follow-up to the Mach8, which finally featured an integrated VGA core, true colour support and a
