. It became an extension (and eventual successor) to the
ATI Wonder series of cards. The first chip in the series was the ATI Mach8. It was essentially a clone of the
IBM 8514/A with a few notable extensions such as Crystal fonts. Being one of the first graphics accelerator chips on the market, the Mach8 did not have an integrated VGA core. In order to use the first Mach8 coprocessor 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 64-bit datapath to internal memory.
