Frink VS Free42

If you like this sort of calculation, check out Frink. "I predict that within 100 years, computers will be twice as powerful, ten thousand times larger, and so expensive that only the five richest kings of Europe will own them." -- Professor John Frink https://frinklang.org/. - Source: Hacker News / 2 months ago

Frink (https://frinklang.org/) is an older language with similar design goals. Frink runs on the JVM and is also available on Android. I use it as a general purpose calculator on my smartphone. - Source: Hacker News / 6 months ago

If I’m reading this correctly, the Frink language has similar features (and also seems darn useful!) https://frinklang.org/. - Source: Hacker News / 6 months ago

When I was in high school units were a key part of science education. Is this no longer the case? Your point about tools that support units is great. Reminds me of https://frinklang.org/. - Source: Hacker News / 7 months ago

My go-to recommendation for an RPN calculator is Free42 (https://thomasokken.com/free42/). It's available for Android, IOS, Mac, Windows, Linux. So you can use the same calculator everywhere. It emulates the real HP-42S calculator very closely, so if you happen to own a real HP-42S, you can switch back and forth without friction. If you don't want to pay the extortion prices for a used HP-42S on eBay, you can pick... Source: 5 months ago

HP15C is amazing but so is the HP42 and HP35S, with the 42 in particular considered by some people to be the best scientific calculator ever made. I have an HP35S which is great. I also have a swiss micros DM42[1] which is an absolutely fantastic calculator based on the Free42[2] opensource emulator. It's much more powerful than the HP42 while remaining 100% compatible. The only downside is the keys are quite a... - Source: Hacker News / 6 months ago

Runs Free42, which is an enhanced HP 42S calculator simulator app written by Thomas Okken. Paid retail bc early models had issues and I’ve been a good little boy and deserve a treat. Market is $150-200. Source: almost 1 year ago

But then I found it was hard going from RPN to the “normal” way my iPhone calculator works. Now I have the Free42 app. No more confusion. https://thomasokken.com/free42/. Source: about 1 year ago

Have you seen Free42, "...a re-implementation of the HP-42S Scientific Programmable Calculator and HP-82240 Printer?" [0] It is available for Android, iOS, Windows, macOS, and Linux. (At one point there was even a version available on Windows Phone 8.) Perhaps it checks your boxes of good RPN calculator, available on all platforms. I don't know how much an HP-42S feels like a 41C. In any event, thank you for ralc.... - Source: Hacker News / about 2 years ago
