Specification

CPU: IBM 386SLC 25 MHz (soldered)
RAM: 4 MB soldered

Despite its name, the 386SLC is a 486SX from a software perspective. It's actually an interesting mix of technologies: you have the 16/24 bit data and address buses from the 386SX, a 486SX compatible instruction set with some enhancements by IBM, a few power saving features and some extra cache over that of a standard Intel 486 CPU. IBM had at one time a license to produce and modify any Intel microprocessor design. They did so for many years, up until at least the early Pentium era.
