    the 1442.

    If you prepared the cards with sequence numbers in columns 73-80
    then you just dropped them into a sorter (if the site had a sorter) -
    otherwise it was less easy. It's the paper tape that someone trod on while
    you were feeding it into the spooler that was less fun.

    No I do not miss those days, nor the overflowing box of waste paper beside the printer under the notice ...

    My first real computer was a PDP-8 with 4K of 12-bit core memory and a
    teletype machine with a 10 char/sec paper tape reader-punch.

    It was actually useful, running the Focal interpretive language. I
    modeled a steamship propulsion system and got us some megabucks of
    business. Actually, I was just a kid at the time.

    Cards were a great improvement over paper tape. Draw a diagonal stripe
    (color coded!) across each subroutine in case you ever droppped them,
    but don't drop them.

    You could look at a 2-foot long card deck and *see* the program
    structure.

    Computers used to boot a lot faster in those days. And had less bugs.

    That is why you put a sequence number in col 73-80. A few passes on the sorter and no problem.

    Sometimes you got lucky, and the dropped deck would smear itself
    across the floor in such a way that, if you were careful, you could
    gather the cards up in sequence.

    The sequence numbers in columns 73-80 were primarily for source code.
    Data decks were usually sorted on various other columns (e.g. customer
    number and/or date).

    I soon gave up on punching sequence numbers in source decks.
    Our programs were subject to frequent modifications that required
    moving large blocks of code around, which meant that the sequence
    numbers became meaningless. You would have to re-punch the deck
    using a utility that re-generated the sequence numbers - and then
    you'd need to run the new deck through an interpreter so you could
    read what was on the cards. It usually wasn't worth the effort.

    My first exposure was paper tape. I typed in my program one week, left

    I treble checked it and could see none.
    I resubmitted it and the next week it ran,. Well sort of. there was a

    on the disk controller card then load up DOS which took extra seconds...

    Booting a Pi can appear to take a long time, but most of that is the
    stuff post-kernel being loaded. I have my own little bare-metal OS for
    the Pi and it loads and can be running in well under a second - unless
    I want USB and that, for some reason takes another second to initialise
    (it's not my code, I stole it from elsewhere - there's only so much you
    can do on your own on something as complex as a Pi these days)

    I like the idea of the Pico 2 and my even look at it - I wrote my little
    OS initially on the 65816 then migrated it to RISC-V and this is a very
    nice RISC-V platform for it - decent RAM, nice peripherals and a 2nd
    CPU too.

    I have also ported it to ARM (on the Pi v1) but it's ARM32 assembler
    and I'm not sure I fancy re-writing it (again) in Thumb32 instructions...

    If you won't be doing that, you can use the Pi 4 PSU.


    No, that is true, and my Pi 4 can just handle two USB SSD drives. JUST.
    Not three though.

    BUT even doing sod all it still draws enough to get its temperature up
    into the 50's°C. As do the drives into the 40s°C

    Which the Pi zero also does

    I think that as a desktop machine Pi 4s and 5s power consumption is
    approaching that of a good intel chipset *for equivalent performance*.

    (these temps may be of interest)

    PI 4B (headless) equipped with 2 SSD

    Disk 2 =44°C

    The rise of ARM caused Intel and AMD to pay a *lot* more attention

    https://arstechnica.com/gadgets/2024/04/what-i-learned-when-i-replaced-my-cheap-pi-5-pc-with-a-no-name-amazon-mini-desktop/

    My core I5 Samsung laptop, now > 10 years old, is soooo much faster
    browsing with Ubuntu and firefox.

    ARM is not a solution to everything.

    Sure GPIO is cool,
    but I have PCI cards with parport for I/O in my normal PCs..
    So maybe for I/O applications just use a <10 dollar Pico2?
    (at least it also has a RISC core?)
    Have not ordered one yet... Not in the online shop here yet last monday.

    Or if no extreme speed is needed I use Microchip PICs:

    Our programs were subject to frequent modifications that required moving large blocks of code around, which meant that the sequence numbers

    This is why you didn’t have the sequence go up in steps of 1, but use
    larger steps, like say 100. That made it easier to insert new cards with in-between numbers.

    It was to pay the patent licence fees for using the hardware decoder. FOSS software decode got around them by not having anyone the patent holders

    Since that was 12 years ago, perhaps the patents have now expired?

    Well MIPs per mW is where its at these days as parallelism can sorta
    increase MIPS to whatever level you want.

    Funnily enuff, the race to more MIPS is likely to drive adoption of
    nuclear power more than any other factor...

    Linux can be as small as you want. Look at Damn Small Linux, for example.
    You can actually build a kernel to run on certain CPUs with no memory- management hardware.

    We went to the moon in the sixties of last century and came back with computing power less than a Raspberry.

    There was actually a whole lot of computing power on the ground, in the
    form of those IBM mainframes, backing up the guys in space. Everything
    they did had to be managed in coordination with ground control, all the
    steps worked out in advance.

    Now astronuts get stuck on the ISS with billions of dollars and
    sup[p]er computers to do the work.

    Bit more Government management of the process back then, bit more trust to private corporations like Boeing, with its stellar reputation for
    relentlessly pursuing reliability over profits, these days.

    Coincidence? You be the judge.

    High quality engineering is a major requirement of space travel.
