Good condition EZ-CZ RAM Cartridge for cz synths.  New batteries.  Tested, Works fine.  Includes box and insert from it's original sale.

Originally it had patches from 'Synthetic Productions' , 1986.   Synthetic Productions is the guy who wrote the Casio CZ book.  I was dismayed to find this cart with no batteries in it, and no patches on it.  On the positive side, there is no battery damage.
