Be sure to add me to your favorites list Korg DPCU-11 "Alternate Collection" ROM Memory Sound Card for DP2000 and DP3000 Digital Pianos, with Sound List. 30 New Sounds for your Korg DP! This is a Korg ROM memory card, "Alternate Collection". It is from the mid 1980's and is in great working condition! It's made specifically for the Korg DP series, the DP2000 and DP3000 models of digital piano keyboards. This card needs no extra Waveform card, as it contains the additional data on it by itself. There are 30 various sounds on it, and it comes with it's sound list card. I have several of these available, all in great performing condition, and good to very good cosmetic condition!
