Hello All,
reading from the data imprinting on MZ-S as the data is printed while the
film is rewinding means that the MZ-S has some amount of 'RAM' like memory.
Does anybody knows how much is it? Another point is, as it saves the
information in memory, why MZ-S does not have a computer interface, USB
or RS232? And, why MZ-S does not print the information while the photo
is taken? This could save the memory and a lot of electronic devices to
detect the frame position, etc,etc,etc?
