I'd like to dig into the numbers a bit more though.

However, if you just care about the speed of specific functions, then you can't go wrong with OS 5.1.x or 5.2.1. Overall it seems if you want the best BASIC performance, then OS 5.0.0 or OS 5.3.1 is the way to go. I only ran prgmRAYTRSPR once because it takes over 30 minutes per run and ain't nobody got time to do that 5 times over! I have yet to retest OSes under 5.3.0 for new prgmRAYTRSPR times. Each test, with the exception of prgmRAYTRSPR was completed 5 times then the times were averaged into the table above. The calculator was plugged in and fully charged the entire time. You can see a description of each test and the full code for each one down below.Īnyways, enjoy the chart: green is the best time and red is the worst time!Įach test was performed from the RAM, on the same calculator (revision pre-A), in the same order, and after a full mem clear. Each one tests a specific function of the calculator.

I was wondering, is TI doing this to our calculator's too? That's why I set up a series of tests and ran them from OS 5.0.0 to 5.4.0. Hey, this is cross post from Cemetech, I thought you guys might find it interesting though!Īs you all know, as technology gets updates with more features, that device typically starts slowing down.
