Hello . This Walkman i know nothing about . It slides up and down, door opens has a white carrier strap and looks clean for its age as in I don't believe it has been dropped.  I got this from it's original owner at an estate sale and was told it worked 20 years ago when he last used it . I have no cassette or headphones to test it so it's AS IS  no returns bid like you are buying it for parts please.  I have posted a lot of pics so please look carefully at them and bid accordingly ☺️
