-------------------------------------------------------------------------------- DualSlim Adapter Board v1.1 Copyright (c) 2022 RBSC -------------------------------------------------------------------------------- About ----- This is the adapter board to connect two slim floppy drives to a single 34-pin FDD interface cable. There could be also a combination of a slim floppy drive, for example MPF820 and a slim Gotek drive, for example SFRM72-DU26. Now you don't need to have 2 drive bays in your MSX computer - you can have 2 drives in a single bay! The 3D printed parts to join 2 slim drives into one solution, suitable for a single drive bay can be found here: https://www.thingiverse.com/thing:5445185 See the pictures in the Pics folder on how to assemble and install the DualSlim setup in MSX2 computer that has a single floppy drive bay. Note the picture for the AX-350 MSX2 fix - you will need to solder one wire for the DualSlim setup in this computer. The video of DualSlim setup in the Yamaha AX-350 computer can be seen here: https://www.youtube.com/watch?v=o-ZJfZNqkJk Parts ----- Beside the circuit board, you will need the following parts: - 4-pin male floppy drive power connector (angled pins) - 34-pin (or longer) dual-row angled pin header with 2.54mm spacing - Two 26-pin FPC ribbon flexible flat cable, 1mm spacing, 100mm long, reverse type! - Two 26-pin FPC/FFC connectors with 1.0mm spacing These parts are available here (at the time of writing): https://www.aliexpress.com/item/1005001582299405.html https://www.aliexpress.com/item/4000373321138.html https://www.aliexpress.com/item/1005001789411803.html https://www.aliexpress.com/item/33043163402.html The slim Gotek drive can be bought from here: https://www.aliexpress.com/item/1005004265960945.html All parts are mounted on the top of the board.
