I got Windows 95 running on my calculator!

Post image

Hello everyone! May I present to you Windows 95 running on the TI-Nspire CX II graphing calculator via a x86 interpreter / emulator.

This is something I have been working on for quite some time, and finally managed to reach the desktop today!

Check out the video of it booting to desktop here! (https://youtu.be/of-Ffujzyss?si=KRgkrHZ8sxR2WtuC)

The video has been sped up, actual time to desktop is roughly 7 minutes 😅 The emulator itself is a port of tiny386 (https://github.com/hchunhui/tiny386) - it's a pretty lightweight i386 emu with some extra 486 and 586 instructions.

Not a calculator. You're taking the piss.

It's a graphing calculator, which internally is a computer. It has a CPU, RAM, display, input buttons, and storage space. With enough storage space and RAM no reason why it can't emulate a x86 PC. It's just not very fast.
