Applications
The ESS ES1868F AudioDrive was a widely used ISA audio chipset in the mid-to-late 1990s, found in many OEM and aftermarket sound cards targeting the budget and mid-range PC market. Cards of this type were designed for ISA-slot desktop PCs running MS-DOS, Windows 3.x, Windows 95, Windows 98, and in some cases Windows XP, and were commonly used for game audio, MIDI playback via the game port, and general multimedia functions. They are used today primarily in retro computing builds, vintage DOS gaming rigs, and legacy industrial or embedded PC systems that require ISA-based audio. The integrated game port supports standard analog joysticks and compatible MIDI adapters.
