Same here (actually had a voyage 200, but same same I guess). It's actually quite insulting that TI kept (and keeps?) selling waaay outdated hardware at horrendous prices. It's the SAP/Oracle business model applied to school hardware.

While I agree on bit about horrible prices, the TI calculators are well suited to their intended task[1] so I will object to the outdated hardware part. Stability is a good thing in the context of classrooms. Why should schools be spending money on replacement hardware, software, and textbooks when the curriculum itself is fundamentally unchanged?[2]

[1] Except the screens on the older models were truly horrible, from a brightness and contrast perspective.

[2] From my recollection, the calculators interfaced with hardware and software from other vendors. Then, of course, there was the vendor lock-in provided by textbook publishers.

Not the same, actually! Unlike the TI-83/84 series, the TI-89, -92, and Voyage-200 all used a 68000 CPU, with a completely different (and much better) operating system.

I wrote a web-based emulator for the Voyage-200 a few years ago: https://woofle.net/v200/
