What's inside

Everything from TempleOS (HolyC, the shell, the editor, the original font and Terry's games), plus:

• A matte-black desktop with a taskbar and a searchable Start menu
• Browser, Files, Paint, Calculator, Calendar, Notes and Settings
• 28 games, including DOOM, Tetris, Chess and Sudoku
• Networking (plain HTTP pages, no HTTPS yet)
• A live CD that can install itself to a disk

Try it

1. Download RelicOS-v0.5.0.iso from the latest release.
2. Make a VM: Other 64-bit, BIOS (not UEFI), 2 GB RAM, an IDE disk if you want to install.
3. Boot the ISO. Press C to try it live, or I to install.

QEMU:

qemu-system-x86_64 -m 2G -smp 2 -cdrom RelicOS-v0.5.0.iso -boot d

Tested in VMware Workstation and QEMU. Real hardware needs a BIOS (legacy) PC; most modern laptops won't boot it.

Click the logo at the bottom left (or press Space) for the Start menu. Type help in the Shell for commands.

Build

Windows, Python 3 and VMware Workstation: tools\relic.ps1 dev boots the dev VM, tools\relic.ps1 iso builds the ISO.
