Shame on me my first cpu was the intel 386 dx 40mhz closely followed by the cyrix 166mhz
Intel i8088. 4.77MHz, 8MHz Turbo mode. Just goes to show you thinking like the i7's "Turbo Mode" aren't anything new.
And no. I'm not kidding.
Intel never made a 40 mhz 386. All the DX40s are AMD chips.
Remember how in those days, chips pre-dated the "ZIF" socket, so processors were more-or-less permenently attached to the motherboard. On most of those AMD 386DX-40 boards, the CPU came soldered on, like today's Atom boards.
