The Turbovision TV Tuner: an add-on for the Turbo Express handheld gaming system.
An excellent accessory that enables time travelers to receive NTSC OTA broadcasts previous to June, 2009. Also has an A/V input to enable use with external devices, like a VCR, Betamax, or Laserdisc player.
NOTE: This Turbovision is missing the antenna and is priced accordingly. There is an external antenna jack, but it doesn't really matter because analog broadcasts are all but non-existent.
