The IBM's 386slc is an INTEL 386sx + 16KB on-chip cache. The SLC is
about 20-40% faster than a SX due to the on-chip cache. Therefore it is
totally compatible with the INTEL 386sx. But the licence agreement
between IBM and INTEL is that IBM can only market the SLC in a system or
on a upgrade board but not as a single chip. So, you cannot purchase the
SLC from IBM.
