And yes, TI calculators have indeed been improving, apparently.
The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the TI-84 features improved hardware. The archive (ROM) is about 3 times as large, and the CPU is about 2.5 times as fast (over the TI-83 and TI-83 Plus)[citation needed]. A USB port and built-in clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port.
That’s web 1.0. Many of us had sites like this on Geocities and Tripod back in the day.
I absolutely love them too because they’re so content dense where as today this would be a 15 item list where you had to click a new page to see each one while reading several paragraphs of what sounds like the most generic, 6th-grade book report on each one “The TI-84 is a calculator. Many people use calculators to do math…”
I love that you can tell they’re a product of passion. Someone was just really into something and wanted to share the info with the world. There’s something beautiful about that.
