Key quotes
· 4 pulledWhen Intel released the 80386 in October 1985, it marked a watershed moment for personal computing.
The 386 was the first 32-bit x86 processor, increasing the register width from 16 to 32 bits and vastly expanding the address space compared to its predecessors.
This wasn't just an incremental upgrade—it was the foundation that would carry the PC architecture for decades to come.
By the mid-1980s, the IBM PC had established x86 as the dominant PC architecture, but the 16-bit 8086/286 processors were hitting their limits.
