So for every area you want to find you have to keep making new programs? Like say you want area of a triangle you need to make another program you can’t put it under area label?
@west4 күн бұрын
That depends on how you have written your program. You could certainly write a program to calculate a variety of areas if you choose to and assign them to different labels. Do whatever you want.

So I stumbled onto a related fix for a non-functional or barely working screen that can be done by opening up the case and removing the PCB just like this. My 32Sii got to where I could see the screen power on but it displayed nothing. The issue was the grey and white foam strips with tiny wires in them at the top and bottom of the lcd . (e.g. 2:59) I thought these were part of the LCD itself (like some sort of flex circuit, and that my screen was toast) but actually they are just a pass through flexible/conformable connector from the pads on the back of the CPU PCB. They are normally held in place likely by adhesive on the bottom of the white foam. But on mine a 1/2" section on the end of the lower one had come loose and moved pretty far towards the keys. The fix was really simple. I put a piece of something in there to push the foam strip back up against the LCD edge. I happened to use a small folded strip of thin card stock from some packaging. (The fold gave it some spring.) But some foam like being used in this video would do the trick as well.

So could you please explain in a video, what Flags are, what they are good for and how to use them properly? Thank you very much indeed!

Got mine some days ago. Having used RPN for years and the Free42 app on my phone for a long time, I knew the functionality of the DM42, which use the Free42 software. I like very much the connectivity of the DM42, meaning I can backup and copy between it and the PC. Using real buttons instead of the touch screen of the phone has me make fewer entering errors. And speaking of buttons: Yes, the buttons are a bit stiffer than the original HP buttons, but they also have a very positive click when engaged. If anything, I tend to prefer the feel of the DM42 buttons to the original HP (some may consider this being heresy). Mind you, that is for the improved keyboard of later years. The first versions had a mediocre keybord feel. Some have criticised that the LCD is not backlit, but this would have meant more battery drain. One of the nice things about the DM42 is that its battery lasts a long time (a year or so (?), depending on use). The insane accuracy is great in theory, but is largely wasted on me. I almost always need magnitudes more than numbers exact to the n'th decimal. The accuracy of a slide rule (three significant numbers) is enough for most of the things I calculate. Of course, the D42 is nerdy galore, since there are free phone apps that can do the same - and Excel can do even more (however, Excel is not for the quick calculation on the fly). But then I also use an old log-log slide rule from time to time (actually it's just as fast or faster for some things involving exponential calculations like 1'st order decay, compound interest, discounting etc.). Given the slide rule was THE calculating tool for the design and construction of all kinds of machines, structures, buildings etc. before the advent of the electronic calculator and the PC/Mac, in my book it's one of the greatest inventions ever. But don't get me started ..... To sum up: I'm perfectly satisfied with the DM42 and it is readily recommended by me.

Thanks for the video. It gives me hope for my beloved 20S I've had since the 80's. My 20S was acting irradically, for instance, sometimes adding 2 numbers correctly, but at other times ignoring the + sign in 2+3 and showing just 23 and waiting for the next command. Soon I will get up the gumption to actually do what your video teaches. Thank you. 6 days later. well, I did everything as shown in ths video except I also drilled the 2 stubs near the batteries, as mentioned below by one of the commentors, which made it much easier to take apart. The first time I did everything as shown in the video, and when I got it all re-assembled and put the batteries in I got the same "All CLR" message, but when I tried to do some simple calcs it still had trouble "seeing" all of the key strokes. So I reassemble it again, put new foam stripes in as shown here, put it back together again, and Ka-Bang it looked like everything worked. I was happy! Two day later I thought I do some calcs, and found that now none of the keys responded, only showing 0.0000. So I give up. HP, that design is so Mickey-Mouse, so disappointing. ....contacts via pressure? rivets vs 4 screws ....anyway, it did work for a while.... interesting exercise.

There is an alternate method for finding Common Logarithms without the use of the L scale. This can be done on a slide rule by using the LL scales which are known as the Log-Log scales. For example, to find the common logarithm of the number 4, first move the right end index of the C scale over 10 on the LL3 scale. Next move the cursor hairline over the number 4 on the LL3 scale. Then read above it on the C scale that the common logarithm of 4 is 0.602. The reason why this works is because common logarithms have the base of 10. The number of interest is 4 in this example. The exponent turns out to be 0.602 read on the C scale. In other words, 10 raised to the exponential power of 0.602 equals the number 4. A logarithm is actually an exponent.

The first calculator I ever owned was a 1970s Omron scientific, an 86SR with a blue-green vacuum fluorescent display and big round buttons. It was a fairly basic machine by today's standards, but it had trig functions, log and exponential and scientific notation. My father had gotten one for himself and then he got me one. I didn't know what most of the advanced functions did yet, but it primed me to learn about those things. I think it was where I learned scientific notation. I used that until sometime in the mid-1980s when it broke--then I used Sharp calculators for a while, then switched to HP's powerful RPL machines in college, a 28S and then a 48SX. The 48 got stolen after a few years; I think I still have the 28S somewhere. But phone apps (including HP emulators!) have mostly taken the place of physical calculators for me.
