This is a Roland M-16C Memory Cartridge, GR-700 Sample Sound version, with banks of alternate patches for the Roland GM-700 guitar synthesizer. It was last tested in August 2023 and worked perfectly. I no longer have the Roland equipment to do a final check. This memory cartridge also works with Roland JX-3P, MKS-10, MKS-20, MKS-30, TR-707, TR-727, TR-909, JX-8P and JX-10 synthesizers and drum machines.

Includes the original box.
