Starting the TI-84 operating system on unfamiliar devices
Starting the TI-84 operating system on unfamiliar devices
I've found a bunch of old, low-quality laptops and tried running quirky operating systems on them. I currently have a Batocera box and a Manjaro server running. SteamOS is pretty straightforward to boot. I'm curious if I could install the TI-84 calculator OS on a laptop or even a Raspberry Pi. Anyone have ideas on how to do that?
The idea of "hardware architectures" feels confusing to you. It’s not something you can really understand because CPUs use different instructions and even different internal setups. x86/x86-64 chips need specific operating systems, while ARM processors work with their own. The TI-84 likely runs a simple real-time interface rather than a full OS.
You'll have to mimic a TI-84, like the Wabbitemu model. It's not possible to execute it directly on any of the devices you mentioned.
It's quite distant, the chip is essentially a design from the 1970s and it requires a very particular hardware setup—like a low-resolution screen that isn't present. Surprisingly, it runs on the Intel 8080, which puts it closer to a modern PC processor than I expected. Nonetheless, it remains extremely outdated.
I believe the nearest option would be to launch the TI nspire OS (ARM based) and then activate the "Ti-84 mode" feature built into the system to mimic a Ti-84 calculator. Alternatively, you could try running a version of Android that likely includes an Ti-84 emulator.
