NES Counter Tester
After the SNES and NES were no longer a competing force in the video game market, Nintendo decided to scale back a bit from their original Nintendo Test Station design and came out with this sleeker upgraded model to test all the NES products people might bring in to a center for servicing. Any businesses that joined on with Nintendo's Service program after a certain time (I can trace it back to 2001 but I don't have a specified date) were given the consolidated test items (This unit and a Control Deck Cartridge for the NES). The unit itself uses a simple pass/fail detect (if the light turns green it passes, if the light turns red it fails) to test audio/video cords, RF adapters and AC adaptors. These tests do not require the counter tester to be plugged into a TV to function though one is required to test the functionality of the NES, games and any controllers. The counter tester has AV cables coming out the back, but don't be fooled; these are used to test the NES unit itself and are not meant to be plugged into a TV!
