Symphony 128 S64 RAM cartridge with original case and documentation from the 1980’s. User serviceable button battery installed in the past year, this unit is 100% functional and operates as expected. Used in a studio setting on a Roland Alpha Juno 2 and will work on other Roland gear, see below for list. From a smoke free environment. Hard to find, it’s the equivalent of having four standard Roland M64-C RAM cards installed at once!
