Sharp RT-442U Cassette Deck with Sharp MDL-127 Microphone.
The Cassette Deck turns on and played back a cassette tape. I tested basic functionality including: Eject, Play, Pause, Stop and these functions worked as expected.
The Microphone and Recording functionality has not been tested.
There is a lot of static noise/hiss when switched on as might be expected from a unit of this age.
Please let me know if you have any questions.
Thanks for looking!
