What is it?

It's an adapter board to connect an HxC floppy emulator (or a real 3-MODE floppy drive) to the Fujitsu FM Towns Marty (1 and 2) console.

With this adapter you will be able to connect an HxC floppy emulator (or a real 3-MODE floppy drive) to the Fujitsu FM Towns Marty (1 and 2) console replacing the old floppy drive which is known to be unreliable and prone to failure.

I will provide instructions and support after sale.

The sale is for the only adapter and doesn't include the floppy and power cables needed to connect the adapter to HxC emulator or real drive which are not included as well.
