Intel 8085 - MCS-85 Family

MCS-85 Family

The 8085 CPU was only one part of a much larger family of chips developed by Intel, for building a complete system. Many of these support chips (or their descendants) later found their use in combination with the 8086 microprocessor. For example, the original IBM PC based on the Intel 8088 processor used many of these chips, and the prominence of IBM PC compatibles is why many of these chips are still in use today, although not as the chips themselves, but with their equivalent functionality embedded into larger VLSI chips, namely the "Southbridge" chips of modern PCs.
