I saw this one on ebay just a few weeks ago, It said "EZ-CZ MEMORY CARTRIDGE(#EZ-4)MADE BY MICROFANATICS,INC". These were made in the late 80's for CZ-3000's and CZ-5000's mostly. The seller indicated the company is longer. ...I gather they are pretty rare. If you've got an ebay account - go to ebay and check out Item # 935515380. <it has the picture and information all there> :0)
