I have for sale a Zemina Expansion Slot and Music Box. The exact operation of the Expansion Slot is a bit unclear, in MSX Mozaïek I read it supposedly passes the primary slot onto the first slot in the expander and exposes an empty subslot from slot 3. The Wiki says it does this by using pin 5 (which is supposedly reserved and flagged as do not use). In my opinion this probably only works on certain (Korean) MSX’s. It does not on the MSX machines I have tested it on. The Music Box does work as expected, it is noisy (as mentioned in the Wiki) and it seems a potentiometer has been installed by a previous owner (to adjust the volume of the OPLL chip going into the MSX). Prices are €60 for the Expansion Slot and €40 for the Music Box. If you get both they are €90 combined.

If you are interested please send me an e-mail. The address is on my profile page.
