Mount a power resistor close to and below the existing thermostat. The thermostat can then be controlled by varying the current in the resistor. Only a few Watts of power should be necessary. Maybe there’s a potential busyness fabricating

I don’t know modern RAM chip organization, but in the old days the bit cells were layed out in a square and an entire row would refresh in parallel. A 1Mb chip would then refresh 1Kb at a time taking 1K refresh cycles for the entire chip.

I easily got each and every word spoken. And had time to think. A lot of old videos have a pleasant pacing. Rob Pike 2018 — on average i got two out of three words and had to spend mental effort on interpolating — that was painful.

I once wrote an assembler in BASIC. We extended the instruction set of a microprocessor by some external circuitry, so the standard assembler was not very useful. BASIC was fine for the job. And it actually worked :)

...but it's not at all the same thing you'd try on the Sinclair that only does radians. Right. Apparently I wasn’t aware of that at the time. Nice to find out here on HN some fourty years later :-)

I think he means rounding to 6 decimal places. If I do that I get 9.326312.

I remember testing various calculators with the sequence 25 sin cos tan atan acos asin to see how close they came back to 25 degrees. The Sinclair showed 42 point something.

What procedure do they actually use? I'd guess SEALs allready have standard procedures for transpoting persons under water in difficult circumstances. Secret procedures probably, so we might never know exactly how they do it.
