    You've never heard of the "skin effect" ?

    The "liner" is a very thin shell that

    I was one.

    In the summer of '57, at the Southern California
    Cooperative Wind Tunnel, swing shift. Pay
    was $1.60 /hr. + 0.12 shift premium. (Gas
    was about 30 cents / gallon).

    Punching an electromechanical "square root Frieden".
    Weight about 50 lbs., price about $1600.

    The "system" featured overlapped I/O:
    remember previous result
    Left hand:enter new caclulation, start
    Right hand: write down previous result
    while the gears churned...

  4. 36 Bits: Fortran made them do it on Remembering 36-bit DECs · · Score: 2
    The IBM 709 /7090 / 7094 were the Fortran machines of the day. They had 36-bit words to get enough precision to do useful computation without resorting to double-precision, which took longer and swallowed too much memory (all 32K WORDS of it).

    IBM adopted 32 bits with the System 360, this was great for Univac which sold many tons of 1107 /1108 machines into the Fortran market.. Nobody cared about characters ..

    the purpose of computers was numbers....

    For many years (maybe still) a Linker option on Unisys 1100/ 2200-series programs is "AFCM" which stands for "Arithmetic Floating Point Compatibility Mode" and which guaranteed bit-for-bit compatibility numeric results with the long-extinct 7094...
