” This is a very rare memory expander (like a memory card) for several mid 80’s Korg synthesizers. It is to be used with the DW-8000, EX-8000, DW-6000, Poly 800 mk2, EX-800, SDVP-1, and SDD-330. It has four banks of storage, each with 64 patches per bank. One awesome feature is that each of the banks can be used as storage for any of the aforementioned units. You can have one bank dedicated to a DW-8000 and another bank dedicated to an EX-800 and so on. Or of course you can use all 256 patches for one synth.
The unit has some cosmetic wear and is missing one of the button tops (which does not affect it’s usage). The unit is completely functional and has been recently used with my Korg DW-8000 (see pictures).”
