I’ve installed 2.55MP on two different TI-84’s. With the release of 2.55, it looks like the TI-84 might have a much longer lifespan that I would have previously guessed when rumors were recently going around that the TI-84 plus silver edition was being discontinued. I thought 2.53 might be the last significant update the TI-84 would see. It’s also interesting to see that TI continues making significant updates to the TI-84 plus. Now, Texas Instruments has almost coded this problem right out of the OS. Until the latest round of upgrades, the biggest drawback to the TI-84 was the large amount of calculator syntax you had to memorize to use the advanced features. This sounds like a fairly straightforward update compared to the major overhaul the TI-84 got last year with 2.53MP. I plan on checking out TI-84 2.55MP tomorrow at school, and I’ll post an update on it when I get a chance to try it out firsthand. The email also said users have the ability to paste these commands back to the home screen so they can be used in other calculations. This new TI-84 OS offers templates (or “wizards” as TI calls them) for statistics features, such as regressions and statistics. The newest release for the TI-84 is 2.55MP. Just received an email from marketing at Texas Instruments alerting me that they released a new operating system for the TI-84 plus a couple of days ago.
