Something we forgot to mention
Intel 8080
2024 marked the 50th anniversary of the introduction of the Intel 8080 processor. It is an important event in the history of IBM-compatible personal computers because it is the immediate predecessor of the Intel 8086 and its brother with the 8-bit bus, the 8088. For many of us, personal computing began with the IBM PC and the x86 architecture, but the true birth of the PC industry was powered seven years earlier by the 8080 in iconic and important products such as the Altair 8800.
If you’re near Silicon Valley, you can visit the Intel Museum through March to see its exhibit about the 8080. Those not close can visit the virtual museum.
Intel took a risk with the 8080 because it was not 100% compatible with the previous 8008. It was close enough that code could be quickly ported (Intel supplied source code converters for the purpose), and the 8080 flourished. It’s safe to say that without the success of the 8080, Intel might have had problems making what would become the big step to x86.
