minus-squarefizzle@quokk.aulinkfedilinkEnglisharrow-up24·3 个月前I don’t know but my supposition is that the ras pi pictured is several powers of magnitude more powerful than the 803.
minus-squaremarcos@lemmy.worldlinkfedilinkarrow-up27·3 个月前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.)
minus-squarelime!@feddit.nulinkfedilinkarrow-up14·3 个月前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.

probably loud af too
oh absolutely, dot matrix printer times 10
