This is an original Yamaha RAM1 cartridge, which lets you store your own patches – doubling the internal capacity of the DX7. It works with the original DX7 and its big brothers, the DX5 and DX1. It's in excellent condition, with hardly any signs of wear; the contacts are clean and corrosion-free; and it's been tested and works perfectly. An excellent and period-authentic way to store your own patches (or the tasty ones you've downloaded from the internet) and give your DX a new lease of life!

You can use it in the DX7II, DX7IID, DX7IIFD and TX802 if you also have the ADP1 adapter (not supplied).

I have two of these units for sale: this listing is for one of them. If you buy both (cos maybe you have a DX1, or maybe you just want to be able to store loads more of your own patches and swap between them...) I will refund 20% of the sale price and combine the postage. So instead of paying 2 x €89 + 2 x €10 postage = €198, you'd pay €152.40. If you'd like to do this, just buy both units and then message me and I'll refund you the difference straight away via Reverb.

I'm based in Spain. Postage within the EU will be €10. If you're outside the EU (including the US and UK) please drop me a message and I'll work out an accurate courier cost for you.
