Best Intellivision Consoles AI pick

Chosen by an AI model from its trained knowledge, with its reasoning.

AI pick (line): Mattel Intellivision (original)

The original Mattel Intellivision is the most widely compatible Intellivision hardware, running the full cartridge library without the third-party lockout found on the Intellivision II.

Not for: Anyone who wants plug-in-and-play on a modern TV without dealing with RF output, or who does not want to repair or replace aging hard-wired controllers.

AI picks by need

For detachable controllers

Mattel Intellivision II (line)

Its controllers unplug, so a worn controller can be swapped without opening the console.

Not for: Collectors who want to play Coleco's Intellivision cartridges, some of which are blocked by its lockout.

For modern TV, no cartridges

AtGames Intellivision Flashback (line)

It has built-in games and replica keypad controllers, and connects directly to current TVs.

Not for: Anyone who wants to play an original cartridge collection, because it has no cartridge slot.

What the AI looks for in Intellivision Consoles

Video output
Stock consoles output RF only. Plan for a TV with an analog tuner, an RF-to-composite converter, or a console with a composite/AV mod. Many modern TVs cannot tune the analog RF signal, or display it poorly.
Controller condition
Confirm every keypad button and all directions on the disc respond. On the original console the controllers are hard-wired. Membranes and cords wear out with age. On the original, a bad controller means opening the console to repair it.
Cartridge compatibility
Choose the original Intellivision or a Sears or INTV variant if you want Coleco-published carts, not the Intellivision II. The Intellivision II's lockout rejects some third-party cartridges.
Region
Match NTSC or PAL hardware to your TV and your cartridges. PAL and NTSC units differ in video output and timing.
Tested working
Prefer a listing that shows the console running a game on screen. Untested units often have dead power supplies, cracked boards or failed controllers.
Power supply
The original has an internal supply. The Intellivision II needs its specific external adapter, so make sure it is included. A wrong or missing adapter can damage the console or leave it unusable.

Brands that matter

  • Mattel: Made the original Intellivision and the Intellivision II.
  • INTV Corporation: Sold the later INTV System III, a revision of the original console.
  • Sears: Sold a rebadged version as the Super Video Arcade.
  • AtGames: Made the Intellivision Flashback plug-and-play console with built-in games.

What to avoid

  • Untested 'as-is' consoles unless you plan to repair them.
  • The Intellivision II if your collection includes Coleco Intellivision cartridges.
  • Listings that leave out the RF switch or, for the Intellivision II, the power adapter.
  • Assuming a stock console will display well on a modern TV without a converter or AV mod.

Questions

Will a stock Intellivision work on my flat-screen TV?

Only if your TV can tune an analog RF channel. Otherwise you need an RF-to-composite converter or a console with a composite mod.

Is the Intellivision II better than the original?

It is smaller and has detachable controllers, but its lockout blocks some third-party games, so the original is the safer choice for the full library.
