In the 1970s CPUs still had wildly different approaches to basic features, with the Intel 8086 being one of them. Whereas the 6502 used separate circuits for operations, and the Intel 8085 a clump of reconfigurable gates, the 8086 uses microcode that configures the ALU along with two lookup tables. This complexity is one of […]
Long before electricity was a common household utility, humanity had been building machines to do many tasks that we’d now just strap a motor or set of batteries onto and think nothing of it. Transportation, manufacturing, agriculture, and essentially everything had non-electric analogs, and perhaps surprisingly, there were mechanical computers as well. Electronics-based computers are […]
