You know your war is running smoothly when you're buying Speak & Spell units off ebay for their vital military components.

as an added bonus the russians can play drug wars on their rocket launchers now.

hey now   when I went to take the AP calc test in 1988 I had to buy one of those and it was about $125

When my son took the same test in 2016 he had to buy one too,,, same exact model and functionality and it cost...$135


so whatever is inside those things, it clearly has the power to shield the unit from Moore's Law

Calculators? Nuts. Have you seen these "plasma lighters?" The circuitry in them could easily be adapted to set off a mine or a bomb anywhere. All a person would have to do is touch the right spot.
 
2022-08-08 1:40:38 PM  
This is not new. They've been doing it for decades. I remember reading about TI chips in their sonar buoys back in the 80's.

This engineer still uses a TI-85. Sometimes its just quicker and more efficient to perform a quick calc that way. It isn't mine, though. It belonged to my wife when she was in high school. I'd still be using an 81, but that finally died about 5 years ago.

Reminds me of when the PS2 first came out. China acquired a bunch of them to use in tandem as an ad hoc supercomputer.

Tetris? You should get Doom running on a TI-83 Plus
 
2022-08-08 1:47:00 PM  
The thing about military hardware is that you build it in large batches and expect it to have a very long shelf life. The expectation is that the next batch of circuits boards you build, likely many years after the initial buildout, is going to require a redesign using contemporary components and potentially getting a cost reduction or enhanced capabilities out of the deal. Apparently Russia is launching cruise missiles with 30 year old circuit boards, and that is probably why one failed and was taken apart by the Ukrainians.

You can't. The best you can do is buy a small CPU and screen which will fit into the plastic case of a pregnancy tester.

We can speculate all we want but we KNOW who has been setting the brand requirements for Russian weapon microprocessor usage; the US College Board. Their influence and strong-arm tactics are far-reaching.

My boss uses the HP because he's used to RPN. When his HP broke about 20 years ago, he tried using the TI. Hates it because it isn't RPN.

Unless your calculator can solve differential equations symbolically or numerically, it's just a toy.

Nah, HP would have a subscription service much like John Deere tractors. Couldn't have your missiles stopping in mid-air because someone forgot to pay the sub.

My wife worked at HP's calculator help desk for several years, so she has a box of misc. calculators.

Fun fact, if you've ever done 80x87 math coprocessor programming, being familiar with RPN makes it an easy transition because 80x87 calculations are all done on a stack like RPN. Load the stack, then operation, operation, operation...

/ no one does that anymore unless they need 80-bit precision.

Nobody needs precision anymore, especially when you define pi as "3"

My 15C from the late '80s still powers up. It would still get some use if Matlab/Octave hadn't already spoiled me.

I wanted to post about how I had Tetris on my TI-85 and how people have got Doom to run on it, instead I find another "Can I get Doom to run on [ridiculous thing]? Yes. Yes I can."

kittyhas1000legs: A chip from 1988?  I guess if it works, it works.


You probably don't want to know how much old silicon is still in use - mainly because, hey, it works, they're cheap as hell, and why buy fancy new? 741 op amps, 555 timers, 2n3904/3960 BJTs, 1N4000 series diodes, MP102 series MOSFETs, 78XX series and LM1100 series regulators, and on and on and on. Why buy a fancy 64-bit microcontroller when an 8 pin PIC will do and costs little to nothing? That sort of thing.

Russia has a fab that it claims is almost production ready... for 65nm chips. Of course, it's been "almost" ready for quite a while now. Intel, at least, actually has working fabs for nodes more recent than two decades ago...

Well, 80 bits (internal) precision is a lot unless you're doing billions of financial transactions a day.

8.2718061255302767487140869206996e-25 precision is enough for most calculations. 64 bits is usually good. IIRC it's only 64 bit external precision per x87 spec. These days it's more useful to have a crapton of shorter word length processors working in concert (because that's all that is needed,) which is what GPUs running quad-word arithmetic are good at.
