jsTIfied Online Emulator Adds Beta TI-84+/SE Support

Early in 2012, I announced jsTIfied, an emulated TI-83 Plus graphing calculator in your browser. Built entirely in Javascript, CSS, and HTML and avoiding the legal pitfalls of a calculator's OS leaving its owner's computer, jsTIfied completely duplicated the functionality of your favorite TI-83+ calculator. You can perform calculations, plot graphs, test programs, and write your own projects. Over the summer, I integrated jsTIfied with the eminent SourceCoder online TI-BASIC editor to allow you to more easily create, test, and publish graphing calculator programs without needing anything besides a web browser. Hardware-wise, the TI-83 Plus is the easiest of the TI-83+/TI-84+ series to emulate, so it was with trepidation that I approached the oft-repeated suggestion that I add TI-84 Plus, TI-84 Plus Silver Edition, and TI-83 Plus Silver Edition support to jsTIfied.

I am happy to announce that after a long weekend of coding, testing, and poring over documentation, I have gotten the first bits of TI-83+SE, TI-84+, and TI-84+SE support in jsTIfied functioning. Thanks to the generous Buckeye and the WabbitEmu project, jsTIfied will display one of four spiffy, high-resolution skins matching the calculator version of the ROM you load. It emulates the extra Flash and RAM (the full 128KB!) of the newer graphing calculators, properly implements features like the realtime clock ports, and much more. However, the new support is still very beta, so a few features are known to be missing. Loading apps and programs to the new models does not yet work, Link Assist is a work-in-progress, and the crystal-based Timer0/Timer1/Timer2 are incompletely implemented. However, I'm making swift strides in adding these new features, so by the time you test jsTIfied some of those issues may be fixed.

I urge you to load up jsTIfied and give it a try. Please be sure to tell me about any bugs you encounter (other than the ones I mentioned), and mention any suggestions to make the emulator more useable. Please also tell your teachers and friends about it, so that they will avoid the pitfall many of my teachers fell into in struggling with the ancient and now-supplanted VTI emulator.
