TV Boy

[2] Resembling a large handheld pad, the systems plug into a TV and operate on either four AA batteries or a 6V power supply (centre negative).

This is true for the Systema and NICS TV Boys, but not for the Akor version, which does not have such external ports at all.

[3] As the TV Boy II has no capacity for external joysticks, only a single player may play using a built-in pad.

The colored bars to the left of the A in the Activision logo remain in some games but the company name is excised.

No replacement game takes its place (it was left non-operational) making the TV Boy II a 126-game handheld console.
