Among all the machines of the 8-bit home computer era which booted straight to a BASIC prompt, there were a very few that went their own way with another language. The Jupiter Ace springs immediately to mind, a diminutive Z80-based machine similar to Sinclair’s ZX81, which booted to FORTH.

The Ace wasn’t a commercial success, but what would have happened had it booted to a more accessible language? It’s a question [jordanhubbard] appears to be trying to answer, with an OS that boots to a Python interpreter.. The OS is Python, and everything on top of it uses the interpreter. Better still, it has a GUI mode.

The OS boots on an x86-64 platform or in QEMU, and appears to have been created using an LLM. There are two build options for the GUI version or the interpreter version. It provides a set of UNIX-like commands for interacting with the OS and disk, something which brings back memories of disk-based systems back in the BASIC days. We’re surprised to see no screenshots of the GUI in action though, an omission he’d do well to correct, we think.

It’s fair to say that in 2026 this is more a bit of fun than a serious OS contender, but maybe someone will run with it. It has competition too, not so long ago we featured a similar OS that runs a BASIC interpreter.

Like many of us, [Austin] finds writing code satisfying — especially if it is challenging. His latest challenge: shoehorn something that looks like Python into 512 bytes. Ok, that didn’t work out, but would you believe 1024 bytes of source code?

The goal was to properly execute a fizzbuzz program using a decidedly Python-like syntax. Since he is only interpreting Python, some things were simplified. In addition, he tried hard to minimize things like whitespace and variable names. Still, there were other things to do, and he borrowed from tips for code golfing.

The resulting code is essentially illegible, but it handles integer variables and literals, assignment, arithmetic, many control structures, functions, and even print. Not bad for 1 K.

Despite being tiny, the parser does a lot, but it does cut corners. No bytecode, no syntax tree, and no error handling. Variables have to be a single lowercase letter. So, ok, it isn’t really Python. But it is something.

Naturally, this reminded us of the obfuscated C code contest. If you really want to go small, we appreciate small Forth.
