I have searched the archives a little further. It appears they are basically the same memory card. It just has to be initialized in a Profex or whatever unit first. I have a line on eight of them, and I want to be sure they are OK to get!
From what I have read on some other sites, the M-512E should work as well. It does not have the internal battery! Might be a real winner, too.
