Some weird PCB in my new Apple II

Can anyone tell me what the heck this is? It's sitting in a new Apple II that I just bought. It seems to be a home-made PCB connected to the auxiliary video connector (probably only for power supply), and it seems to generate a 2 Hz signal into the cassette input (I connected earphones to the cassette in and could hear a 2 Hz ticking).

BTW I bought not only this Apple II, but two others, plus a real Apple II monitor, Apple joystick, paddles, an Apple Silentype (really neat little thing, had never seen or heard of it before), etc.

The Weird PCB

Jak,

It's just a guess, but it could be an amplifier for making sure that whatever is being saved via the cassette input gets to the cassette with plenty of signal strength. Smile
