Selling a new replacement Special Edition “SER-7” ROM EPROM chip to upgrade your vintage Mark 1 DX7! This version includes additional MIDI functionality and a host of other options.
ALSO INCLUDED is a brand-new coin battery holder, so you can replace that dead backup battery and give it a proper home instead of it remaining soldered to the motherboard.
***********************************
DISCLAIMERS: We can’t guarantee that this will repair your DX7, but it might be used to repair an erratic DX7 due to a decaying ROM chip (“bit-rot”). We also cannot accept any liablity per your installing the chip; it is being sold “as-is,” final sale, and no returns.
Please note the notch at the edge to correctly install them on your motherboard. (Obviously, the DX7 is not for sale!) Battery holder will be black or brown.
Please be sure to ask any questions before bidding/purchase.
Thanks!
