MicroPython
MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems
Project mention: Why Lua Beats MicroPython for Serious Embedded Devs | news.ycombinator.com | 2025-07-13it's not an embeddable runtime like Lua
While it's true you can't have multiple MicroPython interpreters running concurrently (or at least not easily; it's not that the design makes this impossible, it's just that all in all MicroPython is fairly young and development focus has been put elsewhere), it is possible to embed MicroPython. Not completely out of the box, needs some glue code etc. See for example https://github.com/micropython/micropython/tree/master/ports....

Project mention: Printer company served you malware for months, called them false positives | news.ycombinator.com | 2025-05-19
That kind of confirmation does exist, it’s called using a hardware wallet, such as those made by Trezor and others.

pycopy
Pycopy - a minimalist and memory-efficient Python dialect. Good for desktop, cloud, constrained systems, microcontrollers, and just everything.

The Tulip Creative Computer[1][2] hits a lot of your points (I'm just a customer). It is definitely not a retro computer with an 8 bit processor, limited memory etc. Instead, it uses modern technology (ESP32S3 microcontroller with megabytes of flash memory and RAM, color touch screen etc.) and runs a modern programming language (MicroPython) that also serves as the operating system.
This particular product might not be exactly what you want, but it shows that you can use these technologies to build a computer that is much simpler than a modern PC in both hardware and software, but is still very capable, and intriguing to use.

Project mention: Wasm2Mpy: Compiling WASM to MicroPython so it can run in Raspberry | news.ycombinator.com | 2024-09-20
Thanks for the explanation this project makes so much more sense now. If people want a little more detail, they have a brief how it works section in readme https://github.com/vshymanskyy/wasm2mpy?tab=readme-ov-file#h...
