Roland M-16C , GR-77B Sample Sound ,Memory cartridge

The M-16C is used to store patches and expand the memory of various vintage Roland synthesizers. This cartridge can be used with the Roland GR-700, JX-3P, MKS-10, MKS-20, MKS-30, TR-707, JX-8P and JX-10.

The M-16C was part of a trio of memory cartridges. Along with the M-16C there is the very rare M-32C, and the M-64C. Inside the M-16C is a 8 x 2K static RAM chip with a lithium battery to power the chip and protect the memory contents.

The original projected life span of the battery was five years, but many of these batteries are still at work twenty-five years later. However, I have seen a few GR-700 circuit boards, and a few M-16Cs, with dead batteries. Replacing the battery is a bit of work, you will need some desoldering tools, and patience getting the pins lined up when installing the new battery.
