One with a cassette player in it that had a mic built in for recording. I found it in the trash.
The other was a small FM/AM alarm clock that was dangerously hot at all times and had a noise as it was an analog clock with the little cards that flipped and the such. My opa gave it to me when he said it got too hot for his liking.
It was not long before I had figured out that if I played the radio really loud on the clock, the cassette mic would record the songs onto whatever tape you had. Be it blank, or with tape over the security gaps on the top, any tape will do.
Hardest part was the timing to start and stop the tape. And making sure you were in as close to total silence as possible as the mic picked everything up.
Even if the hot buzz of the alarm clock motor fighting to flip into the next set of minutes would make it on the tape, the recording/welfare piracy continued. It was the sneezing/siblings walking in/parents making ugly sounds that were the worst as you'd have to stop the tape, rewind to the part of the tape you were using, and wait for the radio station to play the song again, so you might be able to try and tape it again.
I had one radio that did all of this but if I didn't hold a fake adapter into the headphone port at exactly the right angle, nothing worked. I put so much effort into being very still to record songs.
