Just a thought about this supposed digital cartridge (which has been imminent for at least 2 years)- how is it powered? Most digital cameras have a relatively large lithium battery, not a button cell, because they are power hungry- where do you put it? On a wire so it can dangle below the camera? A digital back, with power source, lcd and download socket/card slot would make more sense. I bet we do not see this wonder gadget during 1999. Stewart
