386 Chipsets
Very early 386 motherboards used mostly discrete logic "TTL" ICs. Early 386 chipsets simply merged many of the TTL chips (DMA, IRQ, timers etc) into several highly integrated ICs. The first generation wasn't considered to be totally reliable so they were often mounted in PLCC sockets so expensive motherboards could be easily serviced. These early chipsets often have their top speeds stamped into the tops, and exceeding these limits can result in permanent damage as early VLSI chips were very sensitive. Later 386 chipsets contained reduced numbers of chips and became more specialized, integrating cache controllers, UMB memory management and sometimes support for DRAM interleaving. The last generation of 386 chipsets appeared in the early 90s and were often used in low end 486 motherboards as well. These are often 1 or 2 chip designs and are sometimes lacking performance or features of previous generation high end 386 chipsets, however they are usually rated for operation at higher speeds (40MHz) and work well with fast memory timings.
