ASUS TUSL2-C Motherboard Socket 370 Intel 815EP Chipset PIII Celeron SDRAM ATX

ASUS TUSL2-C Motherboard Socket 370 Intel 815EP Chipset PIII Celeron SDRAM ATX

The ASUS TUSL2-C is an ATX desktop motherboard built around the Intel 815EP chipset and Socket 370 (PGA370) interface, designed to support Intel Pentium III, Pentium III-S, and Celeron processors. It runs a 133 MHz front side bus and supports processors up to 1.2 GHz, making it one of the more capable boards from the peak of the Socket 370 platform.

Applications

The Socket 370 platform was Intel's primary desktop and workstation interface from the late 1990s through the early 2000s, succeeding Slot 1 and supporting the Coppermine and Tualatin generations of Pentium III and Celeron processors. The Intel 815EP chipset integrated graphics support (though this board targets discrete AGP graphics) and provided a clean, stable platform for office workstations and light servers of the era. Today, the TUSL2-C is sought after by vintage PC enthusiasts, retro computing hobbyists, and industrial/embedded users who maintain legacy equipment that requires a reliable Socket 370 board with 133 MHz FSB capability. Its support for the Tualatin-core Pentium III-S makes it particularly desirable among collectors, as Tualatin support required specific board revisions and was not universal across Socket 370 boards.
