Applications

This processor board was used in ISA-bus compatible systems to add or replace CPU functionality. The 386 SX operated at lower clock speeds than its 386 DX counterpart, making it common in cost-conscious business and home computer upgrades. Compatible with PC/XT/AT systems using ISA slots. Historically found in 8086/286-based machines being upgraded to 386-class processing.
