RAFFY'S WEIRD PROJECTS / PROJECT 001

NOT-
CLASSIC
OS

A tiny experimental operating system built from scratch. Not Linux. Not Windows. Not macOS. Not ChromeOS. Just something different.

EARLY DEVELOPMENT

[ 01 / IDEA ]

Computers became enormous. Not-ClassicOS is an experiment in making an operating system small, understandable and fun again.

[ 02 / PRINCIPLES ]

01

Tiny

Designed to remain small enough to test using tiny virtual disks instead of multi-gigabyte virtual machines.

02

From scratch

Not-ClassicOS is intended to have its own kernel and system components rather than being another Linux distribution.

03

Visual

Minimal monochrome graphics, technical information and carefully limited use of colour.

04

Understandable

The project should remain readable enough for its creator to understand how each major component works.

05

Experimental

Not everything needs to behave like Windows, macOS or Linux. Strange ideas are allowed.

06

Open

Source code released publicly under the permissive MIT License.
