Showa Retro Appliances Olympus Microcassette Standard Pearl Corder This appears to be a recording device that uses a unique cassette format standardized by Olympus. It was likely manufactured around 1970. My father used it a little, but it has been stored in the home storage room ever since. In addition to the main unit, which appears to be a recorder, there are various wires like headphones, very small tapes, a speaker, and stethoscope-type earphones. Operation has not been confirmed. It is in an attaché case. The attaché case doesn't close smoothly, perhaps due to rust, but it does close. The parts, main unit, case, etc., show signs of deterioration and dirt. An instruction manual is included. I was planning to dispose of it, but I would like to give it to someone who is interested. Please understand that it may not work before purchasing. Shipping will likely be on the weekend. Thank you.
