I have for sale a very nice, newly assembled, 4MB memory board for compatible Yamaha computers. With the board installed you will have a 4096kB memory mapper! Ideal for VGMPLAY Wink Price is €120.

I also have one original 128kB board for sale that came from my CX-7M.

The following computers have the corresponding connector (although some revisions have the memory onboard ao please check before purchasing). Also I am not entirely certain it will work in MSX1 machines that have just 64kB without a change on the board (possibly just a jumper?).

I just have 1 for now. I can see if there are still any boards available in Russia to assemble some mote or if we can reverse engineer the design.
