# ATI Wonder

The ATI Wonder is a series of video cards for the IBM Personal Computer and compatibles, introduced by ATI Technologies in the mid to late 1980s. These cards were unique at the time as they offered the end user a considerable amount of value by combining support for multiple graphics standards (and monitors) into a single card. The VGA Wonder series added additional value with the inclusion of a bus mouse port, which normally required the installation of a dedicated Microsoft Mouse adapter.
The VGA Wonder series later merged with the ATI Mach series of cards in 1990. The ATI Graphics Ultra (VRAM) and ATI Graphics Vantage (DRAM) cards both featured independent VGA Wonder ASICs in addition to their Mach8 8514 compatible graphics processor. The Graphics Ultra was later renamed the VGA Wonder GT. In 1992, their following product line, the Mach32, integrated the VGA wonder core and coprocessor into a single IC. At this point the VGA Wonder line was cancelled and replaced with a cost reduced DRAM based version of Mach32 known as the ATI Graphics Wonder.
