Thank you for viewing this product. AIWA DR-20 data recorder with digital recording function, audio signal output, and high-speed loading function. This is a retro product manufactured in the Showa era. Although I am not familiar with it, I used it to save and play back data from microcomputers and personal computers on cassette tapes. I switched to a PC quickly and didn't have many opportunities to use it. Therefore, I have kept it carefully without using it until now. I have decided to list it because I believe it is still usable. - Model: DR-20 - Brand: AIWA - Digital Function: Digital Recording - Tape Speed: Normal/High Speed - Output Function: Audio Signal Output - Monitor Function: Monitor/Phase Switching - Operation Buttons: Play/Record/Stop/Fast Forward/Rewind/MOTOR No original box or instruction manual.
