That's a time-consuming thing, but it's quite well possible.
1. Download and install Audacity (free)
2. Connect the audio out of your cassette player to the audio in of your sound card
3. Play and record.
4. Save as wav or mp3
That's real-time: 200 cassettes of 30 minutes = 100 hours.
Splitting into individual tracks, saving them and naming them is another 100 hours.
That's 200 hours combined.
