What's inside

Everything from TempleOS (HolyC, the shell, the editor, the original font and Terry's games) is still there. Relic OS adds a matte black desktop with a taskbar and a searchable Start menu, plus Browser, Files, Paint, Calculator, Calendar, Notes and Settings.

It comes with 28 games, including DOOM, Tetris, Chess and Sudoku. Networking works with plain HTTP pages (no HTTPS yet). The ISO is 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 with Other 64-bit as the OS type, BIOS firmware (not UEFI), 2 GB RAM and 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.
