According to Mouser, Seiko USA is no longer distributing the Seiko LCD
parts. Therefore, they cannot get any more and are instructed to direct
their customers to find replacements out of the other brands that they
carry. There is no direct replacement however, so a slight mod will be
necessary to use a Lumex 16x2 LCD. I will update the parts list on the
yahoo groups site and add directions for the mods. I'll post here when
those files are updated.
