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.
