eBay

This is a system that was sold for use in an Atari 400/800 or Commodore 64 or VIC-20. It connects to the 9 pin game port and the RF antenna port.

It was intended to provide a way to psychologically change attitudes through subliminal messages while watching regular TV programs. The messages would flash in 1/30 of a second - which was too fast to see but your subconscious saw them. (As per the written info that came with the device - it is in one of the photos shown above).

There were 8 programs sold with the system - this auction includes 4 of them. Originally this sold for $89.95 for the interface device and $39.95 for each cartridge. Remember this was 1984 money.

Included is the interface device, antenna cable, 4 cartridges (Career/Success Motivation, Stress Control/Positive Thinking, Sexual Confidence, and Weight Control) all in original packaging. I don;t think it was ever used.

I can't test it and I can't guarantee it will work but it is a complete system.

Question asked: Which system are the included cartridges for?

Answer: Not sure which system. The instructions indicate all mentioned systems for the controller. The controller has 2 F connectors (antenna in and out plus a RCA connector marked computer.

The cartridge is about 5 - 1/2" by 9/16" by 3 3/16". I added a photo of the cartridge with the contacts. There is no indication on the packaging as to which system the cartridges are intended,

The game port connector is a female D-9 connector similar to a serial connector.
