It looks like this deck simply connects to the line-in on your sound card for playback. There is no interface with your motherboard/computer beyond using wires and adapters to connect it to your existing soundcard.
You'll probably have a difficult time controlling the levels being recorded to the tape, among other things, so your $140 might be better spent looking for older but similar-in-function audio equipment.
Though, to be honest, I don't know enough about tape decks to recommend anything. Perhaps someone else can say if there is something better for around $140, because to me the price for this cassette deck seems to be the novelty factor of the equipment being made for a 'personal-computer'.
