    You want to look at bit serial computers.

    PDP8/s (hint "S") had a serial cpu.

    You wouldn't believe how a computor worked a century before 1954. Not
    Babbage's machines but the sort of Computor Babbage was trying to
    replace. He complained that Computors at that time were quite
    inaccurate and very slow at producing even the most basic tables.

    There's always the ball bearing cpu. I can't find this, I'm sure there
    was a video somewhere, it was damn noisy!
