Just picked it up on eBay yesterday, didn't know that Samsung made cassette Walkmans, Will post teardown pictures once here.
Ill be honest, I dont think I have seen any come up on ebay for a long time, if ever. I dont know much about them, but given the Korean decals, I would say these were very specific to that region. It looks very Aiwa-ish at first glance.
Interesting! I have a Samsung mymy MY-S1 it's a nice machine, it has radio and record function no display on the unit though, it's on the remote.
If you are talking about square button on the right, it is A-B repeat basically. It's tracks quite accurately too.
I am referring to the first pictures from Mrp32Dave... it says "Auto DDD call", but i cannot associate it to any meaningful feature
