My Old Friend My TI58c got me through high school, trade school and college but it stopped working some years ago. I missed its simple but powerful programming and was pleasantly surprised to find this app. It's a really good recreation with modern conveniences. I use it every day. Good job and thank you! Edit: It would be nice if I could input text to name the labels for my own programs just like hand writing on the blank yellow cards you inserted into the original calculator
nearly perfect! I love this calculator! It reminds me when I was a student (my math teacher had a ti58c, I couldn't afford it!). I'm wondering if also the other libraries will be implemented/completed sooner or later or not. PS: in the meantime I tried to add some modules to the orignal library, I started with ML-02 (DETERMINANT, MATRIx. & SIMUL EQ) as I found the source code. Unluckily the emulator could have a bug as it doesn't work.
Love this but... I love this calculator and sincerely appreciate the effort that went in to it. It brings back lots of memories! This last update though doesn't fill my nexus 7 screen like the previous version did. I hope we can get that back. Thanks!
Nice Emulator. Very faithful to the original! Lawrence, if you're open to some simple suggestions, then consider breaking "true" emulation and make small concessions to the display. Back in the 70's the LED display technology was a huge limitation and some things that really should have been displayed were omitted. (1) A small status line to display things such as the current "2nd" and "INV" state, as well "Deg/Rad/Grad" would be incredibly useful. (2) In program mode a simple 3 character mnemonic (like "log" or "SUM" etc) could be appended to the numerical op-codes. This would greatly simplify program editing. Some purists might object to any departure from the original display, but it could be as an option.
What a wonderful memories This app brings back the good memories . I have used my TI59 in college some 35 years ago and still have it in one of the drawers. I noticed two issues in my Samsung S6, 1. When touching the display location of the calculator, a message comes up saying "Sorry, no help available for this program" and does not disappear no matter what I do. Second (2.) Issue is the soft menu button always comes up on the keys. If there a way to fix it just below display location or have the user able to select the location.
Coolest app ever. This is NOT my favorite calculator. It IS my favorite app. (It's my 2nd favorite calc.) For a good calculator, and to answer everyone's reservations about this, get the "RealCalc" app. It does what you want. But THIS app, does even more. It's an almost perfect emulation of the Ti-58 programmable calculator. And that's what makes it so special. I can't believe how much work the author put into recreating this wondrous old machine. Here's my deal . . . I have to level some sophisticated avionics systems. I have an ultra-sensitive electronic level that reads out in tenths of a milliradian. I have to insert a shim that corrects for that deviation. So, I have a right-angle triangle with an adjacent of several inches, and an opposite of maybe .0005". Try plugging those numbers into any "triangle" app. Those apps are made for "high-school" shop class trigonomics. This app solved my problem. With a few simple "learning" key strokes, I entered a somewhat complex formula, and could convert a number that was tenths of a milliradian, directly to an appropriate shim size, with one "virtual button". The possibilities are infinite. I could write a book on how cool this app is. Perhaps I did.
15611.5: increase size of tappable button area to see if that reduces complaints about unresponsive buttons; more consistent layout size on larger vs smaller screens; notification status now appears while program is running in background, not just when it stops; CE in error state now clears error state without clearing display.
15457.0: scale layout on phone-sized screens while centring on tablet-sized screens.
