New Free HP 15C Simulator

[billf]

Hi all,

Of possible interest, I just published a new HP 15C simulator that works on most platforms. It's also on the app stores for Android, Linux and Windows. Flutter/Dart source is freely available on Github. under the GPL. It's at https://jrpn.jovial.com

Why YA15CS (yet another 15C simulator)? One nice feature of this one is that the UI scales nicely to any screen size/resolution, because it is entirely drawn using graphics primitives (with the exception of one logo image on the back panel). So, if you want to see what a 15C looks like full-screen on your 8K monitor, this is the program for you!

It can exchange programs with Torsten's Tcl/Tk 15C simulator - I checked in with Torsten several months back, and that was the one request he had. This also let me use a bunch of 15C programs in regression tests.

There's also a nifty (if somewhat primitive) "calculator internals" screen that lets you see the stack, the registers, the matrix values, and the last ten instructions executed. Sorry the scrolling/zoom behavior is wonky -- Google's widget for doing that is, well, a work in progress, but it's good enough for a debug screen.

About MacOS and iOS -- MacOS binaries are on the linked Github site, and easy enough to install if you don't mind Apple warning you about running software that's not from their app store. The iOS version works fine when I run it on an emulator, but installing it on a real phone might be tricky, since Apple has their phone ecosystem locked down pretty tight. I'd be happy to publish it on the Apple app store, but I do balk at paying $100 yearly to be able to give away software - Microsoft and Google asking twenty bucks one-time is fine. (If anyone has an Apple developer account and would be willing to publish, please contact me!)

Cheers,

Bill
