A 1983 British budget home computer from Tangerine, pitched directly against the ZX Spectrum and, despite a shaky and bug-ridden start at home, a lasting success in France, where it held on for years after Britain had moved on.

Its best-remembered game is Defence Force, a fast and faithful take on the arcade classic Defender.

Why it mattered

The Oric is a reminder that home-computer history was regional: a machine that flopped against the Spectrum in Britain yet became a beloved standard across the Channel in France.

Emulating it today

EmulatorsOricutron, MAME
Setup effortTrivial to run (1 on this site's scale)
ControlsThis is a computer-like platform: games may use a joystick or pad, but launching and configuring software often needs a keyboard.
Runs on a handheldYes

The emulator names above are starting points, not a promise that every title or accessory behaves identically. Computer platforms usually add model selection, disk handling and keyboard setup even when CPU emulation itself is mature.

Firmware

This system needs no firmware file. Install an emulator, open a game, and it runs.

How many files you need: none to go and find. No separate firmware file is needed for an ordinary setup.

Firmware details checked 2026-08. Emulator requirements change — see Libretro documentation for the current list.

Where the software is

TOSEC catalogues computer disks and tapes broadly, including many revisions. It is useful for preservation, while a smaller curated selection is usually easier to play.

This site names preservation projects and explains what they are. It does not link to ROM downloads.

Where to start

  1. Zorgon's Revenge 1983 action
  2. Defence Force 1983 shooter

    The Oric's answer to Defender, and its best-remembered game.

  3. Xenon 1 1983 shooter
  4. The Ultra 1985 action

The verdict

For its French library and Defence Force; a modest but characterful catalogue.

Outside a few favourites the library is thin, and much of its best software is French.

Worth it if
Players curious about acorn and the british micro scene and willing to learn how the original machine worked.
Not for
Anyone who wants a large, instantly accessible library and no model, firmware or control decisions.

Scored 3/5 for fun today and 3/5 for historical importance. Those two scores decide the label at the top — a machine can matter enormously and still be no fun.
