I was hoping to find an updated version of this, but I guess computers haven’t gotten any Moore compact since (lemmy.world)

if that's truly from 1957, the whole setup would have several pieces that size. the 803 a few years later was three (one about this size, two a little smaller), plus user console, printer, tape reader. nearly 2000 lbs worth of equipment.

    I don't know but my supposition is that the ras pi pictured is several powers of magnitude more powerful than the 803.

    It certainly is.

    From the wiki:

    "It uses ferrite magnetic-core memory in 4096 or 8192 words of 40 bits, comprising 39 bits of data with parity."

    So a whooping 39kB of memory on the largest option!

    "Tape is read at 500 characters per second and punched at 100 cps."

    Compare that with a micro-SD...

    "The bit time is 6 microseconds, jumps execute in 288 microseconds and simple arithmetic instructions in 576 microseconds."

    And it run and an incredible speed of 1 to 3kHz!

    (And this is overselling the computer, it was slower than what the numbers appear.)

    imagine a tape punch going at 100cps though... even if it's just stamping baudot code that's still 500 actuations per second. that's fuckin terrifying.
